A Simple Experiment that should Refute Creationism?


by Andy Nobles
Is there a simple experiment that can be done whereby actual empirical data can be used to disprove creationist theories on the origin of life? (Young Earth) Yes there is!

If we can show that the human race arose much earlier than 4000 B.C - the rough date given by 'Young Earth' Creationists, and similar to 200,000 B.C. - the date estimated using the evolutionary timescale, then we have effectively disproven creationism. Similarly, if the empirical evidence fits the 4000 B.C. date, then the theory of evolution could be easliy refuted.

Using Mitochondrial DNA - which is passed down from mother to child only, a date of around 200,000 years was given for the age of humanity - the age of the 'Mitochodrial Eve' - the very first human.

However, this date was built mostly on assumptions of the evolutionary time-scale and many dates given by biologists vary.

A great way to know for certain the age of humanity would be to find empirical evidence, in the shape of the mutation rate for mitochondrial DNA.

For example, by comparing the mitochondrial DNA of a man who died 500 years ago with a 20th century man (who are connected by the same Mitochondrial DNA lineage), we would have a definate mutation rate in order to accurately date the age of 'Mitochondrial Eve'. This evidence would also be a perfect way to empirically refute the 'Young Earth' creation theory.

Recently, scientists have conducted this experiment. The results were published in 'Nature Genetics': "The rate and pattern of sequence substitutions in the mitochondrial DNA (mtDNA) control region (CR) is of central importance to studies of human evolution and to forensic identity testing. Here, we report a direct measurement of the intergenerational substitution rate in the human CR. We compared DNA sequences of two CR hypervariable segments from close maternal relatives, from 134 independent mtDNA lineages spanning 327 generational events.

Ten subsitutions were observed, resulting in an empirical rate of 1/33 generations, or 2.5/site/Myr. This is roughly twenty-fold higher than estimates derived from phylogenetic analyses.

This disparity cannot be accounted for simply by substitutions at mutational hot spots, suggesting additional factors that produce the discrepancy between very near-term and long-term apparent rates of sequence divergence. The data also indicate that extremely rapid segregation of CR sequence variants between generations is common in humans, with a very small mtDNA bottleneck.

These results have implications for forensic applications and studies of human evolution." Parsons, Thomas J. 'A high observed substitution rate in the human mitochondrial DNA control region', Nature Genetics vol. 15, April 1997, pp. 363-367.

So the mutation rate is significantly higher than expected, but what date would this give? "The observed substitution rate reported here is very high compared to rates inferred from evolutionary studies. A wide range of CR substitution rates have been derived from phylogenetic studies, spanning roughly 0.025-0.26/site/Myr, including confidence intervals. A study yielding one of the faster estimates gave the substitution rate of the CR hypervariable regions as 0.118 +- 0.031/site/Myr.

Assuming a generation time of 20 years, this corresponds to ~1/600 generations and an age for the mtDNA MRCA of 133,000 y.a. Thus, our observation of the substitution rate, 2.5/site/Myr, is roughly 20-fold higher than would be predicted from phylogenetic analyses.


Using our empirical rate to calibrate the mtDNA molecular clock would result in an age of the mtDNA MRCA of only ~6,500 y.a., clearly incompatible with the known age of modern humans.

Even acknowledging that the MRCA of mtDNA may be younger than the MRCA of modern humans, it remains implausible to explain the known geographic distribution of mtDNA sequence variation by human migration that occurred only in the last ~6,500 years. " Parsons, Thomas J. --'A high observed substitution rate in the human mitochondrial DNA control region', Nature Genetics vol. 15, April 1997, pp. 363-367.

Another scientist comments: "Mitochondrial DNA appears to mutate much faster than expected, prompting new DNA forensics procedures and raising troubling questions about the dating of evolutionary events. ...

Regardless of the cause, evolutionists are most concerned about the effect of a faster mutation rate. For example, researchers have calculated that "mitochondrial Eve"--the woman whose mtDNA was ancestral to that in all living people--lived 100,000 to 200,000 years ago in Africa. Using the new clock, she would be a mere 6000 years old." Ann Gibbons, "Mitochondrial Eve: Wounded, But Not Dead Yet", Science, Vol. 257, 14 August 1992, p. 873.

So the empirical results, which were expected to back up the evolutionary time-scale, have actually refuted it. Not suprisingly, most scientists have tried to sidestep this evidence and come up with theories to explain it.

It's not often in the origins debate, with all it's estimates, bias and assumptions that we get to use empirical evidence like this, so when the evidence strongly supports the creationist theory, you have got to take notice.

Mitochondrial Eve is, however, not likely to be the biblical Eve. This Eve was probably part of an existing population, and merely the female that all of us can trace our ancestry back to, rather then the mother of ALL living. This is due to an extreme bottleneck in human history, which happened, according to the above data in the last 6000 years.

This fits perfectly with the biblical story of the flood, where one family would survive to repopulate the world. The mitochondrial mother is likely therefore to be Noah's wife***.

OBJECTION: But what about Adam?

We also have an ancestral father, who we shall call 'Y chromosome Adam' for now. Unfortunately, we are unsure at the moment how old he is. Here's my prediction: that emprical evidence will date him as young as 6000 years old. Does anybody know of any studies of 'Y' Adam?

OBJECTION: Isn't accepting these scientific dating methods 'picking and choosing' or data mining, where you reject the vast majority of evolutionary timescales, but accept these?

All evolutionary timescales are built on assumptions. This evidence is different in that it uses empirical data:

"The observed substitution rate reported here is very high compared to rates inferred from evolutionary studies." (Parsons 1997, above) The original rate was inferred by evolutionists, and the date of MtDNA Eve was decided by an inferred rate! But now we have an observed rate, which is much higher than the inferred rate. How is this data mining?

Real empirical evidence, which depends on observation will always be more powerful than inference. This empirical dating of Mitochondrial Eve fits in nicely with the creationist model of human origins, but is devastating to the evolutionary model.

OBJECTION: Also, if this is damaging to Evolution, why do the people who produced this data not see this? They are all evolutionists So, they must be very stupid, or you are oversimplifying things.

It's quite understandable that evolutionists should dismiss this evidence, afterall, they operate on a priori assumption that there is a naturalistic explanation for everything:

"We are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counter-intuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is an absolute, for we cannot allow a Divine Foot in the door." Richard Lewontin 'Billions and billions of demons', The New York Review, January 9, 1997, p. 31.

I have yet to be presented with any evidence that I am oversimplifying this argument, although I would be happy to listen to detailed criticism.
***Addendum
Both Jaysen Goertz and Anne C. van Rossum have written to point out that since mtDNA is only passed from mother to daughter, Noah's wife would not be the source. MtDNA passed to a son would not be passed on to offspring.
"All mtDNA after the flood belongs to the biological mother(s) of the three wives."--Jaysen Goetz
This correction does not impact the main argument but only the author's guess as to the identity of the "mitochondrial mother".
***Addendum 2
Re: "All mtDNA after the flood belongs to the biological mother(s) of the three wives." ----This is true only if you agree to the notion that Noah's wife had no further children after the flood. She was, after all, aboard the ark, and with such great life spans, there is no reason to suspect she would cease reproducing after they stepped off it into a new world.

Irreducible Complexity or Preadaption?

What Is a Molecular Machine and Why Is It Irreducibly Complex?
Molecular machines are complex structures located inside of cells or on the surface of cells. One popular example is the bacterial flagella. This whip-like structure is composed of many proteins, and its rotation propels bacteria through their environment. The molecular machine of interest in a recent PNAS article is a protein transport machine located in the mitochondria.2 This machine transports proteins across the membrane of mitochondria so they can perform the very important function of making energy.

Molecular machines are considered to be irreducibly complex. An irreducibly complex machine is made of a number of essential parts, and all these parts must be present for it to function properly. If even one of these parts is missing the machine is non-functional. Evolution, which supposedly works in a stepwise fashion over long periods of time, can’t form these complex machines. Evolution is not goal-oriented; it cannot work towards a specific outcome. If a part of the machine would happen to form by random chance mutation (which itself is not plausible, see Are mutations part of the “engine” of evolution?), but the other parts of the machine were not formed at the same time, then the organism containing that individual part (by itself non-functional) would not have a particular survival advantage and would not be selected for. Since the part offers no advantage to the organism, it would likely be lost from the population, and evolution would be back to square one in forming the parts for the machine. There is essentially no way to collect the parts over time because the individual parts do not have a function (without the other parts) and do not give the organism a survival advantage. Remember, all the necessary parts must be present for the machine to be functional and convey a survival advantage that could be selected for.

So How Can Evolution Account for Irreducibly Complex Molecular Machines?
The inability to find mechanisms that add information to the genome necessary to form parts for the molecular machines and the inability of Darwinian evolution to collect parts for the machines (no direction or goal) have led evolutionists to develop the idea of “pre-adaptation.” Simply stated, “pre-adaptation” is the formation of new parts for a new molecular machine (from currently existing parts that perform another function) before the machine is needed by the organism. Some quotes will help clarify.

Study authors Abigail Clements et al. state, “We proposed that simple “core” machines were established in the first eukaryotes by drawing on pre-existing bacterial proteins that had previously provided distinct functions.”3

Sebastian Poggio, co-author of the study, stated, “[The pieces] were involved in some other, different function. They were recruited and acquired a new function.”4

Wired Science writer, Brandon Keim, puts it this way: “[T]he necessary pieces for one particular cellular machine . . . were lying around long ago. It was simply a matter of time before they came together into a more complex entity.” He also states,

“The process by which parts accumulate until they’re ready to snap together is called preadaptation. It’s a form of “neutral evolution,” in which the buildup of parts provides no immediate advantage or disadvantage. Neutral evolution falls outside the descriptions of Charles Darwin. But once the pieces gather, mutation and natural selection can take care of the rest . . . .”5
These quotes conjure up images of Lego building blocks from my childhood days. The same blocks could be put together in many different ways to form different structures. The study authors suggest proteins that perform one function can be altered (via mutation6) and used for a different function. This eliminates the need to add new genetic information and requires only a modification of current information. Clements et al. state, “This model agrees with Jacob’s proposition of evolution as a “tinkerer,” building new machines from salvaged parts.”7

The problem with this concept is why would evolution “keep” parts that are intermediate between their old function and a new function? The parts or proteins are more or less stuck between a rock and a hard place. They likely don’t perform their old function because they have been altered by mutation, and they don’t perform their new function in a molecular machine because not all the parts are present yet.8 Studies have shown that bacteria tend to lose genetic information that is not needed in their current environment.

For example, the well known microbial ecologist Richard Lenski has shown that bacteria cultured in a lab setting for several years will lose information for making flagella from their genome.9 Bacteria are being supplied with nutrients and do not need flagella to move to find a food source. Bacteria are model organisms when it comes to economy and efficiency, and those bacteria that lose the information to make flagella are at an advantage over bacteria that are taking energy and nutrients to build structures that are not useful in the current environment. Thus, even if new parts for a new molecular machine could be made via mutation from parts or proteins used for another function, the process of natural selection would eliminate them. The parts or proteins no longer serve their old function, and they cannot serve their new function until all the parts for the machine are present.

In particular, notice the use of verbs in the quotes above, such as drawing on, recruited, came together, and snap together. These are all action verbs that invoke the image of someone or something putting the parts together. Going back to the Lego analogy, an intelligent designer (me!) is required to put the Lego blocks together to form different structures. Just leaving the blocks lying on the floor or shaking them up in their storage container doesn’t result in anything but a big mess of blocks! Although the powers to “tinker” and “snap together” are conferred on mutation and natural selection, they are incapable of designing and building molecular machines.

Conclusion
Pre-adaptation is another “just so” evolutionary story that attempts to avoid the problems of necessary information gain and the goal-less nature of evolution. It fails to answer how parts that are intermediate between their old and new functions would be selected for and accumulated to build a molecular machine.

Michael Gray, cell biologist at Dalhousie University, states, “You look at cellular machines and say, why on earth would biology do anything like this? It’s too bizarre. But when you think about it in a neutral evolutionary fashion, in which these machineries emerge before there’s a need for them, then it makes sense.”10 It only makes sense if you start with the presupposition that evolution is true and confer powers to mutation and natural selection that the evidence shows they do not have.

Clements et al. write, “There is no question that molecular machines are remarkable devices, with independent modules capable of protein substrate recognition, unfolding, threading, and translocation through membranes.”11 The evidence is clear, as Romans 1:20 states, that the Creator God can be known through His creation. Many people will stand in awe of the complexities of molecular machines and still deny they are the result of God’s handiwork. But that doesn’t change the truth of His Word that He is the Creator of all things.

The Bacteria Flagellum-quick summary

The most important person to bring the concept of irreducible complexity to the forefront of the scientific agenda is the biochemist Michael J. Behe of Lehigh University in the United States. In his book Darwin's Black Box: The Biochemical Challenge to Evolution, published in 1996, Behe examines the irreducibly complex structure of the cell and a number of other biochemical structures, and reveals that it is impossible to account for these by evolution. According to Behe, the real explanation of life is intelligent design.

Behe's book was a serious blow to Darwinism. In fact, Peter van Inwagen, Professor of Philosophy at the University of Notre Dame, stresses the importance of the book in this manner:

If Darwinians respond to this important book by ignoring it, misrepresenting it, or ridiculing it, that will be evidence in favor of the widespread suspicion that Darwinism today functions more as an ideology than as a scientific theory. If they can successfully answer Behe's arguments, that will be important evidence in favor of Darwinism.349

One of the interesting examples of irreducible complexity that Behe gives in his book is the bacterial flagellum. This is a whip-like organ that is used by some bacteria to move about in a liquid environment. This organ is embedded in the cell membrane, and enables the bacterium to move in a chosen direction at a particular speed.

Scientists have known about the flagellum for some time. However, its structural details, which have only emerged over the last decade or so, have come as a great surprise to them. It has been discovered that the flagellum moves by means of a very complicated "organic motor," and not by a simple vibratory mechanism as was earlier believed. This propeller-like engine is constructed on the same mechanical principles as an electric motor. There are two main parts to it: a moving part (the "rotor") and a stationary one (the "stator").


An electric motor-but not one in a household appliance or vehicle. This one is in a bacterium. Thanks to this motor, bacteria have been able to move those organs known as "flagella" and thus swim in water.This was discovered in the 1970s, and astounded the world of science, because this "irreducibly complex" organ, made up of some 240 distinct proteins, cannot be explained by chance mechanisms as Darwin had proposed.

The bacterial flagellum is different from all other organic systems that produce mechanical motion. The cell does not utilize available energy stored as ATP molecules. Instead, it has a special energy source: Bacteria use energy from the flow of ions across their outer cell membranes. The inner structure of the motor is extremely complex. Approximately 240 distinct proteins go into constructing the flagellum. Each one of these is carefully positioned. Scientists have determined that these proteins carry the signals to turn the motor on or off, form joints to facilitate movements at the atomic scale, and activate other proteins that connect the flagellum to the cell membrane. The models constructed to summarize the working of the system are enough to depict the complicated nature of the system.

The complicated structure of the bacterial flagellum is sufficient all by itself to demolish the theory of evolution, since the flagellum has an irreducibly complex structure. If one single molecule in this fabulously complex structure were to disappear, or become defective, the flagellum would neither work nor be of any use to the bacterium. The flagellum must have been working perfectly from the first moment of its existence. This fact again reveals the nonsense in the theory of evolution's assertion of "step by step development." In fact, not one evolutionary biologist has so far succeeded in explaining the origin of the bacterial flagellum although a few tried to do so.

The bacterial flagellum is clear evidence that even in supposedly "primitive" creatures there is an extraordinary design. As humanity learns more about the details, it becomes increasingly obvious that the organisms considered to be the simplest by the scientists of nineteenth century, including Darwin, are in fact just as complex as any others.

Billions of People in Thousands of Years?

Creationists are often asked, “How is it possible for the earth’s population to reach 6.5 billion people if the world is only about 6,000 years old, and if there were just two humans in the beginning?” Here is what a little bit of simple arithmetic shows us.

One Plus One Equals Billions
Let us start in the beginning with one male and one female. Now let us assume that they marry and have children and that their children marry and have children and so on. And let us assume that the population doubles every 150 years. Therefore, after 150 years there will be four people, after another 150 years there will be eight people, after another 150 years there will be sixteen people, and so on. It should be noted that this growth rate is actually very conservative. In reality, even with disease, famines, and natural disasters, the last doubling took only 35 years. The world's current growth rate is about 1.14%/year, representing a doubling time of 61 years. We can expect the world's population of 6.5 billion to become 13 billion by 2067 if current growth continues

After 32 doublings, which is only 4,800 years, the world population would have reached almost 8.6 billion. That’s 2 billion more than the current population of 6.5 billion people, which was recorded by the U.S. Census Bureau on March 1, 2006. This simple calculation shows that starting with Adam and Eve and assuming the conservative growth rate previously mentioned, the current population can be reached well within 6,000 years.

Impact of the Flood
We know from the Bible, however, that around 2500 BC (4,500 years ago) the worldwide Flood reduced the world population to eight people. But if we assume that the population doubles every 150 years, we see, again, that starting with only Noah and his family in 2500 BC, 4,500 years is more than enough time for the present population to reach 6.5 billion.

From two people, created about 6,000 years ago, and then the eight people, preserved on the Ark about 4,500 years ago, the world’s population could easily have grown to the extent we now see it—over 6.5 billion. Evolutionists are always telling us that humans have been around for hundreds of thousands of years. If we did assume that humans have been around for 50,000 years and if we were to use the calculations above, there would have been 332 doublings, and the world’s population would be a staggering figure—a one followed by 100 zeros; that is

10,000,000,000,000,000,000,000,000,000,000,
000,000,000,000,000,000,000,000,000,000,
000,000,000,000,000,000,000,000,000,000,
000,000,000.
This figure is truly unimaginable, for it is billons of times greater than the number of atoms that are in the entire universe! Such a calculation makes nonsense of the claim that humans have been on earth for tens of thousands of years.

Simple, conservative arithmetic reveals clear mathematical logic for a young age of the earth. From two people, created around 6,000 years ago, and then the eight people, preserved on the Ark about 4,500 years ago, the world’s population could have grown to the extent we now see it—over 6.5 billion.

With such a population clearly possible (and probable) in just a few thousand years, we could actually ask the question, “If humans were around millions of years ago, why is the population so small?” This is a question that evolution supporters must answer.

Dr. Monty White is now a young-earth creationist; however, as a young Christian, he believed in theistic evolution. Since 2000, he has been the CEO of Answers in Genesis—UK.

Does Radiometric Dating Prove the Earth Is Old?

The presupposition of long ages is an icon and foundational to the evolutionary model. Nearly every textbook and media journal teaches that the earth is billions of years old.

Using radioactive dating, scientists have determined that the Earth is about 4.5 billion years old, ancient enough for all species to have been formed through evolution.1
The earth is now regarded as between 4.5 and 4.6 billion years old.2
The primary dating method scientists use for determining the age of the earth is radioisotope dating. Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth. This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).

What Is Radioisotope Dating?
Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements. There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms. For example, uranium will radioactively decay through a series of steps until it becomes the stable element lead. Likewise, potassium decays into the element argon. The original element is referred to as the parent element (in these cases uranium and potassium), and the end result is called the daughter element (lead and argon).

The Importance of Radioisotope Dating
The straightforward reading of Scripture reveals that the days of creation (Genesis 1) were literal days and that the earth is just thousands of years old and not billions. There appears to be a fundamental conflict between the Bible and the reported ages given by radioisotope dating. Since God is the Creator of all things (including science), and His Word is true (“Sanctify them by Your truth. Your word is truth,” John 17:17), the true age of the earth must agree with His Word. However, rather than accept the biblical account of creation, many Christians have accepted the radioisotope dates of billions of years and attempted to fit long ages into the Bible. The implications of doing this are profound and affect many parts of the Bible.

How Radioisotope Dating Works
Radioisotope dating is commonly used to date igneous rocks. These are rocks which form when hot, molten material cools and solidifies. Types of igneous rocks include granite and basalt (lava). Sedimentary rocks, which contain most of the world’s fossils, are not commonly used in radioisotope dating. These types of rocks are comprised of particles from many preexisting rocks which were transported (mostly by water) and redeposited somewhere else. Types of sedimentary rocks include sandstone, shale, and limestone.

Uranium to lead decay sequence Uranium-238 Thorium-234 Protactinium-234 Uranium-234 Thorium-230 Radium-226 Radon-222 Polonium-218 Lead-214 Bismuth-214 Polonium-214 Lead-210 Bismuth-210 Polonium-210 Lead-206 (stable)

Uranium-238 (238U) is an isotope of uranium. Isotopes are varieties of an element that have the same number of protons but a different number of neutrons within the nucleus. For example, carbon-14 (14C) is a particular isotope. All carbon atoms have 6 protons but can vary in the number of neutrons. 12C has 6 protons and 6 neutrons in its nucleus. 13C has 6 protons and 7 neutrons. 14C has 6 protons and 8 neutrons. Extra neutrons often lead to instability, or radioactivity. Likewise, all isotopes (varieties) of uranium have 92 protons. 238U has 92 protons and 146 neutrons. It is unstable and will radioactively decay first into 234Th (thorium-234) and finally into 206Pb (lead-206). Sometimes a radioactive decay will cause an atom to lose 2 protons and 2 neutrons (called alpha decay). For example, the decay of 238U into 234Th is an alpha decay process. In this case the atomic mass changes (238 to 234). Atomic mass is the heaviness of an atom when compared to hydrogen, which is assigned the value of one. Another type of decay is called beta decay. In beta decay, either an electron is lost and a neutron is converted into a proton (beta minus decay) or an electron is added and a proton is converted into a neutron (beta plus decay). In beta decay the total atomic mass does not change significantly. The decay of 234Th into 234Pa (protactinium-234) is an example of beta decay.

The radioisotope dating clock starts when a rock cools. During the molten state it is assumed that the intense heat will force any gaseous daughter elements like argon to escape. Once the rock cools it is assumed that no more atoms can escape and any daughter element found in a rock will be the result of radioactive decay. The dating process then requires measuring how much daughter element is in a rock sample and knowing the decay rate (i.e., how long it takes the parent element to decay into the daughter element—uranium into lead or potassium into argon). The decay rate is measured in terms of half-life. Half-life is defined as the length of time it takes half of the remaining atoms of a radioactive parent element to decay. For example, the remaining radioactive parent material will decrease by 1/2 during the passage of each half-life (1→1/2→1/4→1/8→1/16, etc.). Half-lives as measured today are very accurate, even the extremely slow half-lives. That is, billion-year half-lives can be measured statistically in just hours of time. The following table is a sample of different element half-lives.

Parent Daughter Half-life
Polonium-218 Lead-214 3 minutes
Thorium-234 Protactinium-234 24 days
Carbon-14 Nitrogen-14 5,730 years
Potassium-40 Argon-40 1.25 billion years
Uranium-238 Lead-206 4.47 billion years
Rubidium-87 Strontium-87 48.8 billion years

Science and Assumptions
Scientists use observational science to measure the amount of a daughter element within a rock sample and to determine the present observable decay rate of the parent element. Dating methods must also rely on another kind of science called historical science. Historical science cannot be observed. Determining the conditions present when a rock first formed can only be studied through historical science. Determining how the environment might have affected a rock also falls under historical science. Neither condition is directly observable. Since radioisotope dating uses both types of science, we can’t directly measure the age of something. We can use scientific techniques in the present, combined with assumptions about historical events, to estimate the age. Therefore, there are several assumptions that must be made in radioisotope dating. Three critical assumptions can affect the results during radioisotope dating:

1.The initial conditions of the rock sample are accurately known.
2.The amount of parent or daughter elements in a sample has not been altered by processes other than radioactive decay.
3.The decay rate (or half-life) of the parent isotope has remained constant since the rock was formed.
The Hourglass Illustration
Radioisotope dating can be better understood using an illustration with an hourglass. If we walk into a room and observe an hourglass with sand at the top and sand at the bottom, we could calculate how long the hourglass has been running. By estimating how fast the sand is falling and measuring the amount of sand at the bottom, we could calculate how much time has elapsed since the hourglass was turned over. All our calculations could be correct (observational science), but the result could be wrong. This is because we failed to take into account some critical assumptions.

1.Was there any sand at the bottom when the hourglass was first turned over (initial conditions)?
2.Has any sand been added or taken out of the hourglass? (Unlike the open-system nature of a rock, this is not possible for a sealed hourglass.)
3.Has the sand always been falling at a constant rate?
Since we did not observe the initial conditions when the hourglass time started, we must make assumptions. All three of these assumptions can affect our time calculations. If scientists fail to consider each of these three critical assumptions, then radioisotope dating can give incorrect ages.

The Facts
We know that radioisotope dating does not always work because we can test it on rocks of known age. In 1997, a team of eight research scientists known as the RATE group (Radioisotopes and the Age of The Earth) set out to investigate the assumptions commonly made in standard radioisotope dating practices (also referred to as single-sample radioisotope dating). Their findings were significant and directly impact the evolutionary dates of millions of years.3

A rock sample from the newly formed 1986 lava dome from Mount St. Helens was dated using Potassium-Argon dating. The newly formed rock gave ages for the different minerals in it of between 0.5 and 2.8 million years.4 These dates show that significant argon (daughter element) was present when the rock solidified (assumption 1 is false).

Mount Ngauruhoe is located on the North Island of New Zealand and is one of the country’s most active volcanoes. Eleven samples were taken from solidified lava and dated. These rocks are known to have formed from eruptions in 1949, 1954, and 1975. The rock samples were sent to a respected commercial laboratory (Geochron Laboratories in Cambridge, Massachusetts). The “ages” of the rocks ranged from 0.27 to 3.5 million years old.5 Because these rocks are known to be less than 70 years old, it is apparent that assumption #1 is again false. When radioisotope dating fails to give accurate dates on rocks of known age, why should we trust it for rocks of unknown age? In each case the ages of the rocks were greatly inflated.

Isochron Dating
There is another form of dating called isochron dating, which involves analyzing four or more samples from the same rock unit. This form of dating attempts to eliminate one of the assumptions in single-sample radioisotope dating by using ratios and graphs rather than counting atoms present. It does not depend on the initial concentration of the daughter element being zero. The isochron dating technique is thought to be infallible because it supposedly eliminates the assumptions about starting conditions. However, this method has different assumptions about starting conditions and can give incorrect dates.

If single-sample and isochron dating methods are objective and reliable they should agree. However, they frequently do not. When a rock is dated by more than one method it may yield very different ages. For example, the RATE group obtained radioisotope dates from ten different locations. To omit any potential bias, the rock samples were analyzed by several commercial laboratories. In each case, the isochron dates differed substantially from the single-sample radioisotope dates. In some cases the range was more than 500 million years.6 Two conclusions drawn by the RATE group include:

1.The single-sample potassium-argon dates showed a wide variation.
2.A marked variation in ages was found in the isochron method using different parent-daughter analyses.
If different methods yield different ages and there are variations with the same method, how can scientists know for sure the age of any rock or the age of the earth?

In one specific case, samples were taken from the Cardenas Basalt, which is among the oldest strata in the eastern Grand Canyon. Next, samples from the western Canyon basalt lava flows, which are among the youngest formations in the canyon, were analyzed. Using the rubidium-strontium isochron dating method, an age of 1.11 billion years was assigned to the oldest rocks and a date of 1.14 billion years to the youngest lava flows. The youngest rocks gave a billion year age the same as the oldest rocks! Are the dates given in textbooks and journals accurate and objective? When assumptions are taken into consideration and discordant (disagreeing or unacceptable) dates are not omitted, radioisotope dating often gives inconsistent and inflated ages.

Two Case Studies
The RATE team selected two locations to collect rock samples to conduct analyses using multiple radioisotope dating methods. Both sites are understood by geologists to date from the Precambrian (supposedly 543–4,600 million years ago). The two sites chosen were the Beartooth Mountains of northwest Wyoming near Yellowstone National Park, and the Bass Rapids sill in the central portion of Arizona’s Grand Canyon. All rock samples (whole rock and separate minerals within the rock) were analyzed using four radioisotope methods. These included the isotopes potassium-argon (K-Ar), rubidium-strontium (Rb-Sr), samarium-neodymium (Sm-Nd), and lead-lead (Pb-Pb). In order to avoid any bias, the dating procedures were contracted out to commercial laboratories located in Colorado, Massachusetts, and Ontario, Canada.

In order to have a level of confidence in dating, different radioisotope methods used to date a rock sample should closely coincide in age. When this occurs, the sample ages are said to be concordant. In contrast, if multiple results for a rock disagree with each other in age they are said to be discordant.

Beartooth Mountains Sample Results
Geologists believe the Bearthooth Mountains rock unit to contain some of the oldest rocks in the United States, with an estimated age of 2,790 million years. The following table summarizes the RATE results.7

The results show a significant scatter in the ages for the various minerals and also between the isotope methods. In some cases, the whole rock age is greater than the age of the minerals, and for others, the reverse occurs. The potassium-argon mineral results vary between 1,520 and 2,620 million years (a difference of 1,100 million years).

Bass Rapids Sill Sample Results
The 11 Grand Canyon rock samples were also dated commercially using the most advanced radioisotope technology. The generally accepted age for this formation is 1,070 million years. The RATE results are summarized in the following table.8



The RATE results differ considerably from the generally accepted age of 1,070 million years. Especially noteworthy is the multiple whole rocks potassium-argon isochron age of 841.5 million years while the samarium-neodymium isochron gives 1,379 million years (a difference of 537.5 million years).

Possible Explanations for the Discordance
There are three possible explanations for the discordant isotope dates.

1.There may be a mixing of isotopes between the volcanic flow and the rock body into which the lava intrudes. There are ways to determine if this has occurred and can be eliminated as a possible explanation.
2.Some of the minerals may have solidified at different times. However, there is no evidence that lava cools and solidifies in the same place at such an incredibly slow pace. Therefore this explanation can be eliminated.
3.The decay rates have been different in the past than they are today. The following section will show that this provides the best explanation for the discordant ages.
New Studies
New studies by the RATE group have provided evidence that radioactive decay supports a young earth. One of their studies involved the amount of helium found in granite rocks. Granite contains tiny zircon crystals, which contain radioactive uranium (238U), which decays into lead (206Pb). During this process, for each atom of 238U decaying into 206Pb, eight helium atoms are formed and migrate out of the zircons and granite rapidly.

Within the zircon9 crystals, any helium atoms generated by nuclear decay in the distant past should have long ago migrated outward and escaped from these crystals. One would expect the helium gas to eventually diffuse upward out of the ground and then disappear into the atmosphere. To everyone’s surprise, however, large amounts of helium have been found trapped inside zircons.10

The decay of 238U into lead is a slow process (half-life of 4.5 billion years). Since helium migrates out of rocks rapidly, there should be very little to no helium remaining in the zircon crystals.

Why is so much helium still in the granite? One likely explanation is that sometime in the past the radioactive decay rate was greatly accelerated. The decay rate was accelerated so much that helium was being produced faster than it could have escaped, causing an abundant amount of helium to remain in the granite. The RATE group has gathered evidence that at some time in history nuclear decay was greatly accelerated.

The experiments the RATE project commissioned have clearly confirmed the numerical predictions of our Creation model.... The data and our analysis show that over a billion years worth of nuclear decay has occurred very recently, between 4000 and 8000 years ago.11
Confirmation of this accelerated nuclear decay having occurred is provided by adjacent uranium and polonium radiohalos that formed at the same time in the same biotite flakes in granites.12 Radiohalos result from the physical damage caused by radioactive decay of uranium and intermediate daughter atoms of polonium, so they are observable evidence that a lot of radioactive decay has occurred during the earth’s history. However, because the daughter polonium atoms are only short-lived (for example, polonium-218 decays within 3 minutes, compared to 4.47 million years for uranium-238), the polonium radiohalos had to form within hours to a few days. But in order to supply the needed polonium atoms to produce these polonium radiohalos within that timeframe, the nearby uranium atoms had to decay at an accelerated rate. Thus hundreds of millions of years worth of uranium decay (compared to today’s slow decay rate) had to have occurred within hours to a few days to produce these adjacent uranium and polo-nium radiohalos in granites.

The RATE group suggested that this accelerated decay took place during the Creation Week or during the Flood. Accelerated decay of this magnitude would result in immense amounts of heat being generated in rocks. Determining how this heat was dissipated presents a new and exciting opportunity for creation research.

Conclusion
The best way to learn about history and the age of the earth is to consult the history book of the universe—the Bible. Many scientists and theologians accept a straightforward reading of Scripture and agree that the earth is about 6,000 years old. It is better to use the infallible Word of God for our scientific assumptions than to change His Word in order to compromise with “science” that is based upon man’s fallible assumptions. True science will always support God’s Word.

Based on the measured helium retention, a statistical analysis gives an estimated age for the zircons of 6,000 ± 2,000 years. This age agrees with literal biblical history and is about 250,000 times shorter than the conventional age of 1.5 billion years for zircons. The conclusion is that helium diffusion data strongly supports the young-earth view of history.13
It must also be concluded, therefore, that because nuclear decay has been shown to have occurred at grossly accelerated rates when molten rocks were forming, crystallizing and cooling, the radiometric methods cannot possibly date these rocks accurately based on the false assumption of constant decay through earth history at today’s slow rates. Thus the radiometric dating methods are highly unreliable and don’t prove the earth is old.

The origin of life: DNA and protein

by Dr. Gary Parker

First published in
Creation: Facts of Life

Chapter 1: Evidence of creation

The two basic parts of the tumbled pebble and the arrowhead we considered are hard and soft rock. Two basic parts of every living system are DNA and protein.

DNA is the famous molecule of heredity. It has been on the cover of Time magazine, and we often hear news stories about it. This is the molecule that gets passed down from one generation to the next. Each of us starts off as a tiny little ball about the size of a period on a printed page. In that tiny ball, there are over six feet (2m) of DNA all coiled up. All of our characteristics (height, skin color, etc.) are “spelled out” in that DNA.

What are proteins? Proteins are the molecules of structure and function. Hair is mostly protein; skin cells are packed full of proteins; the enzymes that break down food and build it up are proteins; the filaments that slide together to make muscles work are proteins.

So, DNA and protein are two basic “parts” of every living system. When you get down to a virus, that’s all you find—DNA and protein. (In some viruses, RNA substitutes for DNA.) The DNA molecules code for the protein molecules that make us what we are. That same principle applies to all life forms: viruses, plants, animals, as well as human beings.


Figure 2-A. DNA is built like a string of pearls, whose links (specifically the bases G, C, A, and T) act like alphabet letters that “spell out” hereditary instructions.

Figure 2-B. Proteins are chains of amino acids. Each chain coils into a special shape that has some special function: muscle contraction, digestion, oxygen transport, holding skin together, etc.

My students study all of the details,2 but DNA and protein molecules are really quite simple in their basic structure. If you can picture a string of pearls, you can picture DNA: it is a chain of repeating units. Fig. 2-A is a diagram of a DNA molecule. The parts that look like railroad box cars are sugar and phosphate groups, and the parts that stick out from each box car in the chain are groups called bases.

Proteins are built in about the same way. Proteins are also chains of repeated units. As shown in Fig. 2-B, the links in protein chains are called amino acids. In all living things, inherited chains of DNA bases are used to line up chains of amino acids. These amino-acid chains are the protein molecules responsible for structure and function. For example, chains of several hundred DNA bases tell the cell how to make a protein called hemoglobin, and that protein functions as the oxygen carrier in red blood cells. In short form, DNA→protein→trait, and that relationship is the physical basis of all life on earth.

Now, what about that relationship between DNA and protein? How did it get started? Evolutionists picture a time long ago when the earth might have been quite different. They imagine that fragments of DNA and fragments of protein are produced. These molecules are supposed to “do what comes naturally” over vast periods of time. What’s going to happen? Will time, chance, and chemical reactions between DNA and protein automatically produce life?

At first you might think so. After all, nothing is more natural than a reaction between acids and bases. Perhaps you’ve used soda (a base) to clean acid from a battery. The fizz is an acid-base reaction. So is using “Tums” to neutralize stomach acid. Nothing is more common than reactions between acids and bases. If you just wait long enough, acid-base reactions will get DNA and protein working together, and life will appear—right? Wrong! Just the opposite.

The problem is that the properties of bases and acids produce the wrong relationship for living systems. Acid-base reactions would “scramble up” DNA and protein units in all sorts of “deadly” combinations. These reactions would prevent, not promote, the use of DNA to code protein production. Since use of DNA to code protein production is the basis of all life on earth, these acid-base reactions would prevent, not promote, the evolution of life by chemical processes based on the inherent properties of matter.

These wrong reactions have produced serious problems for Stanley Miller, Sidney Fox, and other scientists trying to do experiments to support chemical evolution. Almost all biology books have a picture of Miller’s famous spark chamber (Fig. 3). In it, Miller used simple raw materials and electric sparks to produce amino acids and other simple molecules—the so-called “building blocks of life.” Some newspapers reported that Miller had practically made “life in a test tube.”

Figure 3. Left to time, chance, and their chemical properties, the bases of DNA and amino acids of proteins would react in ways that would prevent, not promote, the evolution of life. In the same way, reactions among molecules in Miller’s famous “spark chamber” would destroy any hope of producing life. Living systems must constantly repair the chemical damage done to them, and when biological order loses out to inherent chemical processes, death results—even though a dead body has all the right molecules in the right places in the right amounts at the right times (almost!). View full-size.


Miller’s experiment was brilliant, and I loved to tell my students about it. But then I came to see there were just three little problems: he had the wrong starting materials, used the wrong conditions, and got the wrong results.

What do I mean by “wrong starting materials?” Miller left out oxygen. Why? Because of the scientific evidence? No. He left it out because he knew oxygen would destroy the very molecules he was trying to produce. It’s hard for us to realize how “corrosive” oxygen is, since most modern living things depend on it. But oxygen is so valuable to life precisely because it’s so chemically reactive, and aerobic living things today have systems to protect themselves against the harmful effects of oxygen, while using its chemical power to their advantage. (Anaerobic organisms and most viruses are quickly destroyed by contact with oxygen.)

A. I. Oparin, the Russian biochemist who “fathered” modern views of spontaneous generation or chemical evolution, knew oxygen in the atmosphere would prevent evolution. But he also “knew,” by faith in Engels’ materialistic philosophy (the view that matter is the only reality), that creation was impossible (there was no spiritual dimension). As an act of faith, then, Oparin believed evolution must have occurred, and as a concession to his faith, he left oxygen out. Science has not been kind to that belief. We find oxidized rocks, suggesting an oxygen atmosphere, as deep as we can dig.

Furthermore, methane (CH4) and ammonia (NH3), two prime gases in the Miller spark chamber, could not have been present in large amounts. The ammonia would be dissolved in the oceans, and the methane should be found stuck to ancient (deep) sedimentary clays. It’s not there! Those who still believe in chemical evolution are aware of these problems (as is Miller himself), so they are simply trying (as yet unsuccessfully) to simulate the origin of life using different starting materials. (Carbon monoxide and hydrogen cyanide are two popular, if unlikely, gases being used today.)

Wrong conditions? Miller used an electric spark to get the gas molecules to combine, and that works. Problem: the same electric spark that puts amino acids together also tears them apart. And it’s much better at destroying them than making them, meaning, few if any amino acids would actually accumulate in the spark chamber. Miller, a good biochemist, knew that, of course. So he used a common chemist’s trick. He drew the gases out of the spark chamber and into a “trap” that would save the amino acids from destruction by the same electric spark that made them. Using product removal (the principle of LeChatelier or law of mass action) to increase yield is ordinary chemical practice, but it depends on intervention by informed intelligence. Miller was supposed to be demonstrating that the gases could make the “building blocks of life” all by themselves without any outside help, yet his outside, intelligent help was necessary to save the molecules from their destructive chemical fate. (Moreover, creating life in a test tube as a consequence of intelligent design would offer more support to creation than to evolution.)

Wrong results? How could that be? Miller wanted to make amino acids, and he got amino acids (along with sugars and a few other things). How could those results be wrong?

The proteins in living cells are made of just certain kinds of amino acids, those that are “alpha” (short) and “left-handed.” Miller’s “primordial soup” contained many long (beta, gamma, delta) amino acids and equal numbers of both right-and left-handed forms. Problem: just one long or right-handed amino acid inserted into a chain of short, left-handed amino acids would prevent the coiling and folding necessary for proper protein function. What Miller actually produced was a seething brew of potent poisons that would absolutely destroy any hope for the chemical evolution of life.

The “left-handed amino acid problem” is particularly well-known to evolutionists, and several have been trying to solve it. One brilliant researcher, after working unsuccessfully for years on the problem, just smiled and chuckled when asked about it: “Perhaps God is left-handed.” He may have been closer to the truth than he realized. From what we know about the chemistry of the molecules involved, it really looks like the molecules could never put themselves together into living cells apart from the careful selection, engineering genius, and deliberate design of the Transcendent Creative Intelligence we call God!

Chemistry, then, is not our ancestor; it’s our problem. When cells lose their biological order and their molecules start reacting in chemical ways, we die. A dead body contains all the molecules necessary for life and approximately the right amount of each, but we never see a “road kill” get up and walk off because sunlight energy shining on the carcass made all the molecules of life start working together again. What’s lost at death are balance and biological order that otherwise use food to put us together faster than chemistry tears us apart! (See Parker,3,4; Bliss and Parker5; Wilder-Smith6; and Thaxton, Bradley, and Olsen7 for details.)

Time and chance are no help to the evolutionist either, since time and chance can only act on inherent chemical properties. Trying to throw “life” on a roll of molecular dice is like trying to throw a “13” on a pair of gaming dice. It just won’t work. The possibility is not there, so the probability is just plain zero.


Figure 4. All living cells use groups of three DNA bases as code names for amino-acid R-groups. But all known chemical reactions between these molecules (e.g., base-acid) would prevent, not promote, development of this coding relationship. Is the hereditary code, then, the logical result of time, chance, and the inherent properties of matter (like the water-worn pebble); or does it have the irreducible properties of organization (like the arrowhead) that scientists ordinarily associate with plan and purpose?

The relationship between DNA and protein required for life is one that no chemist would ever suspect. It’s using a series of bases (actually taken three at a time) to line up a series of R-groups (Fig. 4). R-groups are the parts of each amino acid that “stick out” along the protein chain. “R” stands for the “variable radical,” and variable it is! An R-group can be acid; it can be a base; it can be a single hydrogen atom, a short chain, a long chain, a single ring, a double ring, fat-soluble, or water-soluble!

The point is this: there is no inherent chemical tendency for a series of bases (three at a time) to line up a series of R-groups in the orderly way required for life. The base/R-group relationship has to be imposed on matter; it has no basis within matter.

The relationship between hard and soft rock in the arrowhead in Fig. 1 had to be imposed from the outside. All of us could recognize that matter had been shaped and molded according to a design that could not be produced by time, chance, and weathering processes acting on the hard and soft rock involved. In the same way, our knowledge of DNA, protein, and their chemical properties should lead us to infer that life also is the result of plan, purpose, and special acts of creation.

Let me use a simpler example of the same kind of reasoning. Suppose I asked you this question: “Can aluminum fly?” Think a moment. Can aluminum fly? I’m sure that sounds like a trick question. By itself, of course, aluminum can’t fly. Aluminum ore in rock just sits there. A volcano may throw it, but it doesn’t fly. If you pour gasoline on it, does that make it fly? Pour a little rubber on it; that doesn’t make it fly either. But suppose you take that aluminum, stretch it out in a nice long tube with wings, a tail, and a few other parts. Then it flies; we call it an airplane.

Did you ever wonder what makes an airplane fly? Try a few thought experiments. Take the wings off and study them; they don’t fly. Take the engines off, study them; they don’t fly. Take the little man out of the cockpit, study him; he doesn’t fly. Don’t dwell on this the next time you’re on an airplane, but an airplane is a collection of non-flying parts! Not a single part of it flies!

What does it take to make an airplane fly? The answer is something every scientist can understand and appreciate, something every scientist can work with and use to frame hypotheses and conduct experiments. What does it take to make an airplane fly? Creative design and organization.

Figure 5. Living cells use over 75 special kinds of protein and RNA molecules to make one protein following DNA’s instructions. What we know about airplanes convinces us that their flight is the result of creative design. What scientists know about the way living cells make protein suggests, just as clearly, that life also is the result of creative design. (Drawing after Bliss and Parker. 1979. Origin of Life. Master Books, Colorado Springs, Colorado.) View full-size.

Take a look at the features of a living cell diagrammed in Fig. 5. Don’t worry; I am not going to say much about this diagram. Just notice the DNA molecule in the upper left circle and the protein in the lower right. What are all the rest of those strange looking things diagrammed in the cell? Those represent just a few of the molecules that a cell needs to make just one protein according to the instructions of just one DNA molecule. A cell needs over 75 “helper molecules,” all working together in harmony, to make one protein (R-group series) as instructed by one DNA base series. A few of these molecules are RNA (messenger, transfer, and ribosomal RNA); most are highly specific proteins.8

When it comes to “translating” DNA’s instructions for making proteins, the real “heroes” are the activating enzymes. Enzymes are proteins with special slots for selecting and holding other molecules for speedy reaction. As shown in Fig. 5 (Circle 3), each activating enzyme has five slots: two for chemical coupling (c, d), one for energy (ATP), and, most importantly, two to establish a non-chemical three-base “code name” for each different amino acid R-group (a, b). You may find that awe-inspiring, and so do my cell-biology students!

And that’s not the end of the story. The living cell requires at least 20 of these activating enzymes I call “translases,” one for each of the specific R-group/code name (amino acid/tRNA) pairs. Even so, the whole set of translases (100 specific active sites) would be (1) worthless without ribosomes (50 proteins plus rRNA) to break the base-coded message of heredity into three-letter code names; (2) destructive without a continuously renewed supply of ATP energy to keep the translases from tearing up the pairs they are supposed to form; and (3) vanishing if it weren’t for having translases and other specific proteins to re-make the translase proteins that are continuously and rapidly wearing out because of the destructive effects of time and chance on protein structure!

But let’s forget about all the complexity of the DNA-protein relationship and just remember two simple points. First, it takes specific proteins to make specific proteins. That may remind you of the chicken-and-egg problem: how can you get one without the other? That problem is solved, if the molecules needed for “DNA-protein translation” are produced by creation.

Second, among all the molecules that translate DNA into protein, there’s not one molecule that is alive. There’s not a single molecule in your body that’s alive. There’s not a single molecule in the living cell that’s alive. A living cell is a collection of non-living molecules! What does it take to make a living cell alive? The answer is something every scientist recognizes and uses in a laboratory, something every scientist can logically infer from his observations of DNA and protein. What does it take to make a living cell alive? Creative design and organization!

Only creative acts could organize matter into the first living cells. But once all the parts are in place, there is nothing “magical” or “mysterious “ in the way cells make proteins. If they are continually supplied with the right kind of energy and raw materials, and if all 75-plus of the RNA and protein molecules required for DNA-protein “translation” are present in the right places at the right times in the right amounts with the right structure, then cells make proteins by using DNA’s base series (quite indirectly!) to line up amino acids at the rate of about two per second. In ways scientists understand rather well, it takes a living cell only about four minutes to “crank out” an average protein (500 amino acids) according to DNA specifications.

Scientists also understand how airplanes fly. For that very reason, no scientist believes that airplanes are the result of time, chance, and the properties of aluminum and other materials that make up the airplane. Flying is a property of organization, not of substance. A Boeing 747, for example, is a collection of 41/2 million non-flying parts, but thanks to design and creation (and a continuous supply of energy and of repair services!), it flies.

Similarly, “life” is a property of organization, not of substance. A living cell is a collection of several billion non-living molecules, and death results when a shortage of energy or a flaw in the operational or repair mechanisms allows inherent chemical processes to destroy its biological order.

It’s what we do know and can explain about aluminum and the laws of physics that would convince us that airplanes are the products of creation, even if we never saw the acts of creation. In the same way, it’s what we do know and can explain about DNA and protein and the laws of chemistry which suggests that life itself is the result of special creation.

My point is not based on design per se, but on the kind of design we observe. As creationists point out, some kinds of design, such as snowflakes and wind-worn rock formations, do result from time and chance—given the properties of the materials involved. Even complex relationships, such as the oxygen-carbon dioxide balance in a sealed aquarium, can result from organisms “doing what comes naturally,” given the properties of living things. But just as clearly, other kinds of design, e.g., arrowheads and airplanes, are the direct result of creative design and organization giving matter properties it doesn’t have and can’t develop on its own. What we know about the DNA-protein relationship suggests that living cells have the created kind of design.

In the well-known Scientific American book, Evolution, Dickerson9 seems to support my point (without meaning to, I’m sure). After describing the problems in producing the right kinds of molecules for living systems, he says that those droplets that by “sheer chance” contained the right molecules survived longer. He continues, “This is not life, but it is getting close to it. The missing ingredient is …”

What will he say here? The “missing ingredient” is … one more protein? … a little more DNA? … an energy supply? … the right acid-base balance? No, he says: “The missing ingredient is an orderly mechanism … ”An orderly mechanism! That’s what’s missing—but that’s what life is all about! As I stated before, life is not a property of substance; it’s a property of organization. The same kind of reasoning applies to the pyramids in Egypt, for example. The pyramids are made of stone, but studying the stone does not even begin to explain how the pyramids were built. Similarly, until evolutionists begin to explain the origin of the “orderly mechanism,” they have not even begun to talk about the origin of life.

When it comes to the evolutionary origin of that orderly mechanism, Dickerson adds, we have “no laboratory models: hence one can speculate endlessly, unfettered by inconvenient facts.” With “no laboratory models” to provide data, the case for the evolution of life must be based on imagination. But, as Dickerson admits, “We [evolutionists] can only imagine what probably existed, and our imagination so far has not been very helpful.”

The case for creation, however, is not based on imagination. Creation is based instead on logical inference from our scientific observations, and on simple acknowledgment that everyone, scientists and laymen alike, recognize that certain kinds of order imply creation.

Let me give you another example of the same sort of reasoning. Imagine that you have just finished reading a fabulous novel. Wanting to read another book like it, you exclaim to a friend, “Wow! That was quite a book. I wonder where I can get a bottle of that ink?” Of course not! You wouldn’t give the ink and paper credit for writing the book. You’d praise the author, and look for another book by the same writer. By some twist of logic, though, many who read the fabulous DNA script want to give credit to the “ink (DNA base code) and paper (proteins)” for composing the code.

In a novel, the ink and paper are merely the means the author uses to express his or her thoughts. In the genetic code, the DNA bases and proteins are merely the means God uses to express His thoughts. The real credit for the message in a novel goes to the author, not the ink and paper, and the real credit for the genetic message in DNA goes to the Author of Life, the Creator, not to the creature (Romans 1:25).

Creation thus stands between the classic extremes of mechanism and vitalism. Mechanists, including evolutionists, believe that both the operation and origin of living things are the results of the laws of chemistry which reflect the inherent properties of matter. Vitalists believe that both the operation and origin of living systems depend on mysterious forces that lie beyond scientific description. According to creation, living things operate in understandable ways that can be described in terms of scientific laws—but, such observations include properties of organization that logically imply a created origin of life.

In this sense, the Bible proved to be, as it often has, far ahead of its time. Right down to the last century, most scientists and philosophers believed living things were made of something fundamentally different from non-living. But Genesis 1–2 tells us living things, human beings included, were just made of “dust of the ground.” Indeed, scientists now recognize that living cells are composed of only a few simple elements. It’s not the stuff (“dust”) we’re made of that makes us special; it’s the way we’re put together. It’s not the metal and glass that make an airplane fly, nor the ink and paper that write a novel. Similarly, it’s not the “dust” that makes life, but the way it’s put together with creative design and organization. And when that organization is lost, we return to “dust,” the simple elements that make us up, just as other created objects break down into their simpler parts when left to the ravages of time, chance, and chemistry.

The creationist, then, recognizes the orderliness that the vitalist doesn’t see. But he doesn’t limit himself to only those kinds of order that result from time, chance, and the properties of matter, as the evolutionist does. Creation introduces levels of order and organization that greatly enrich the range of explorable hypotheses and turn the study of life into a scientist’s delight. Science requires an orderliness in nature. One of the real emotional thrills of my changing from evolution to creation was realizing both that there are many more levels of order than I had once imagined and that order in nature, and a mind in tune with it, were guaranteed by God Himself. It’s no wonder that explicit Biblical faith gave initial success to the founding fathers of modern experimental science (a couple of centuries before evolution came along to shift the basis toward time and chance).

If the evidence for the creation of life is as clear as I say it is, then other scientists, even those who are evolutionists, ought to see it—and they do.

I once took my students to hear Francis Crick, who shared a Nobel prize for the discovery of DNA’s structure. After explaining why life could not and did not evolve on earth, he argued instead for “directed panspermia,” his belief that life reached earth in a rocket fired by intelligent life on some other planet. Crick admitted that his view only moved the creation-evolution question back to another time and place, but he argued that different conditions might have given life a chance to evolve that it did not have on earth.10

Creationists are pleased that Crick recognizes the same fatal flaws in chemical evolution that they have cited for years, but creationists also point out that the differences between “chemical chemistry” and “biological chemistry” are wrapped up with the fundamental nature of matter and energy and would apply on other planets as well as on earth.11

That opinion seems to be shared in part by the famous astronomer Sir Fred Hoyle,12 who made the news under the heading “There must be a God.” Hoyle and his colleague, Chandra Wickramasinghe, independently reached that conclusion after their mathematical analyses showed that believing that life could result from time, chance, and the properties of matter was like believing that “… a tornado sweeping through a junk yard might assemble a Boeing 747 from the materials therein.” (Remember what it takes to make an airplane fly?)

Drawing the logical inference from our scientific knowledge, both scientists concluded that “it becomes sensible to think that the favorable properties of physics on which life depends are in every respect deliberate.” (Emphasis Hoyle’s.) But both were surprised by their results. Hoyle called himself an agnostic, and, in the same article, Wickramasinghe said he was an atheistic Buddhist who “… was very strongly brainwashed to believe that science cannot be consistent with any kind of deliberate creation.”

My purpose in quoting these scientists (and others later on) is not, of course, to suggest that they are creationists who would endorse all my views. Rather, it is simply to show that experts in the field, even when they have no preference for creationist thinking, at least agree with the creationists on the facts. And when people with different viewpoints agree, we can be pretty sure what the facts are. I also want to show that scientists who are not creationists are able to see that creation is a legitimate scientific concept, whose merits deserve to be compared with those of evolution.

In that light, I’d like to call your attention to a fascinating and revolutionary book, Evolution: A Theory in Crisis, by a prominent molecular biologist, Dr. Michael Denton.13 In a television program we did together, and in our extensive personal conversations, Dr. Denton describes himself as a child of the secular age who desires naturalistic explanations when he can find them. But when it comes to the origin of life, Dr. Denton explains with authority and stark clarity that evolutionists are nowhere near a naturalistic explanation at present. After comparing the genetic programs in living things to a library of a thousand volumes encoding a billion bits of information and all the mathematically intricate algorithms for coordinating them, Dr. Denton refers to the chemical evolution scenario as “simply an affront to reason,” i.e., an insult to the intelligence! (p. 351).

He openly and frankly states that the thesis of his book is “anti-evolutionary” (p. 353), but it seems to me that he is cautiously taking a step even further. The first chapter of his book is titled “Genesis Rejected,” and he would react very strongly against being called a creationist, but in his honest analysis of the creation-evolution controversy through history, Dr. Denton freely admits that many of the scientific views of the early creationists have been vindicated by modern discoveries in science.

Take William Paley’s classic argument that design in living things implies a Designer just as clearly as design in a watch implies a watchmaker. Denton states, “Paley was not only right in asserting an analogy between life and a machine, but also remarkably prophetic in guessing that the technological ingenuity realized in living systems is vastly in excess of anything yet accomplished by man.” (Emphasis added.) Then Denton goes on to summarize his thinking on life’s origin (p. 341) as follows:

The almost irresistible force of the analogy has completely undermined the complacent assumption, prevalent in biological circles over most of the past century, that the design hypothesis can be excluded on the grounds that the notion is fundamentally a metaphysical a priori concept and therefore scientifically unsound. On the contrary, the inference to design is a purely a posteriori induction based on a ruthlessly consistent application of the logic of analogy. The conclusion may have religious implications, but it does not depend on religious presuppositions. (Emphasis added.)

Now that’s quite an admission! Even though he would deny any leaning toward a Christian concept of creation, this leading molecular biologist sees quite plainly that a scientific concept of creation can be constructed, just as I’ve said, using the ordinary tools of science, logic, and observation. (In fact, Denton intimates that creation scientists have shown more respect than evolutionists for empirical evidence and a “ruthlessly consistent” application of logic!)

It’s also true, as Denton concludes, that creation may have religious implications, but so does evolution, and that should not prevent our evaluating their scientific merits on the basis of logic and observation alone. Notice, I am not suggesting at this point that I’ve somehow “proved evolution is false and creation is true.” Rather, I’m simply suggesting that the creation-evolution controversy, far from being a dead issue, is a live and lively question that demands serious scientific consideration.

Even that “simple” suggestion may prove too much for some. In what seems to me a real fear of discussing the scientific weaknesses of evolution and the scientific strengths of creation, it has become fashionable among anti-creationists to accuse creation scientists of misquoting authorities. After spending a fabulous four-hour evening with Dr. and Mrs. Denton, I then quoted him extensively in a conference (April 1987) in Sydney, Australia, which he attended and at which he spoke briefly after my presentations. Whatever others might say, at least Michael Denton doesn’t believe I misquoted him! (If you’re concerned about misquotation, see Dr. Gish’s thorough new book documenting evolutionists’ misquotations, Creation Scientists Answer Their Critics.14)

But again, my point: I am not quoting Dr. Denton as if he agreed with all my thinking. On the contrary, my point is that a fellow scientist who shares neither my basic assumptions nor conclusions regarding world-and-life view, nevertheless recognizes that the concept of creation can be explained scientifically, and that the concept has at least some scientific merit.

Dr. Denton is, of course, not alone in that stand. In a short but thought-provoking article, British physicist H. S. Lipson15 first expresses his interest in life’s origin, then his feeling—quite apart from any preference for creation—that “In fact, evolution became in a sense a scientific religion; almost all scientists have accepted it and many are prepared to ‘bend’ their observations to fit with it.”

After wondering how well evolution has stood up to scientific testing, Lipson continues: “To my mind, the theory [evolution] does not stand up at all.” Then he comes to the heart of the issue: “If living matter is not, then, caused by the interplay of atoms, natural forces, and radiation [i.e., time, chance, and chemistry], how has it come into being?” After dismissing a sort of directed evolution, Lipson concludes: “I think, however, that we must go further than this and admit that the only acceptable explanation is creation.” (Emphasis his.)

Like Hoyle and Wickramasinghe, Lipson is a bit surprised and unhappy with his own conclusion. He writes, “I know that this [creation] is anathema to physicists, as indeed it is to me … . ” But his sense of honesty and scientific integrity forces him to conclude his sentence thus: “… but we must not reject a theory that we do not like if the experimental evidence supports it.” That’s the spirit I’d like to encourage in this book: a willingness to look openly at all sides of an issue, to draw the most logical inference from the weight of evidence, and to follow “truth” wherever it might lead, regardless of personal preference and preconceptions.

By the way, let me assure you that not all who see the evidence of creation are unhappy about it! Witness Dr. Dean Kenyon. Dr. Kenyon is a molecular biologist whose area of research interest is specifically the origin of life. His book on life’s origin, Biochemical Predestination, opened with laudatory phrases for Darwinian evolution, and he taught evolution at San Francisco State University for many years.

A couple of students in Dr. Kenyon’s class once asked him to read a book on creation science. He didn’t want to, but, thanks to their polite persistence, he resolved to read it and refute it. But, as he told me in person, he read it and couldn’t refute it. Instead, Dr. Kenyon got interested in creation science and began a re-evaluation of the scientific evidence, which finally led him to the happy conclusion that life, including his, is here as a result of creation, the deliberate plan and purpose of a personal Creator God! He still presents the evidence cited in favor of evolution in his classes, but he also allows his students to weigh that against the evidence that favors creation.

Like mine, Dr. Kenyon’s change from evolution to creation took a long time and involved re-examination of much more than just the evidence from molecular relationships within living cells. Let’s take a look now at some evidence of creation from other areas of biology.

Creation: ‘Where’s the Proof?’


Over the years, many people have challenged me with a question like:

‘I’ve been trying to witness to my friends. They say they don’t believe the Bible and aren’t interested in the stuff in it. They want real proof that there’s a God who created, and then they’ll listen to my claims about Christianity. What proof can I give them without mentioning the Bible so they’ll start to listen to me?’

Briefly, my response is as follows.

Evidence
Creationists and evolutionists, Christians and non-Christians all have the same evidence—the same facts. Think about it: we all have the same earth, the same fossil layers, the same animals and plants, the same stars—the facts are all the same.

The difference is in the way we all interpret the facts. And why do we interpret facts differently? Because we start with different presuppositions. These are things that are assumed to be true, without being able to prove them. These then become the basis for other conclusions. All reasoning is based on presuppositions (also called axioms). This becomes especially relevant when dealing with past events.

Past and Present
We all exist in the present—and the facts all exist in the present. When one is trying to understand how the evidence came about (Where did the animals come from? How did the fossil layers form? etc.), what we are actually trying to do is to connect the past to the present.

However, if we weren’t there in the past to observe events, how can we know what happened so we can explain the present? It would be great to have a time machine so we could know for sure about past events.

Christians of course claim they do, in a sense, have a ‘time machine’. They have a book called the Bible which claims to be the Word of God who has always been there, and has revealed to us the major events of the past about which we need to know.

On the basis of these events (Creation, Fall, Flood, Babel, etc.), we have a set of presuppositions to build a way of thinking which enables us to interpret the evidence of the present.

Evolutionists have certain beliefs about the past/present that they presuppose, e.g. no God (or at least none who performed acts of special creation), so they build a different way of thinking to interpret the evidence of the present.

Thus, when Christians and non-Christians argue about the evidence, in reality they are arguing about their interpretations based on their presuppositions.

That’s why the argument often turns into something like:

‘Can’t you see what I’m talking about?’

‘No, I can’t. Don’t you see how wrong you are?’

‘No, I’m not wrong. It’s obvious that I’m right.’

‘No, it’s not obvious.’ And so on.

These two people are arguing about the same evidence, but they are looking at the evidence through different glasses.

It’s not until these two people recognize the argument is really about the presuppositions they have to start with, that they will begin to deal with the foundational reasons for their different beliefs. A person will not interpret the evidence differently until they put on a different set of glasses—which means to change one’s presuppositions.

I’ve found that a Christian who understands these things can actually put on the evolutionist’s glasses (without accepting the presuppositions as true) and understand how they look at evidence. However, for a number of reasons, including spiritual ones, a non-Christian usually can’t put on the Christian’s glasses—unless they recognize the presuppositional nature of the battle and are thus beginning to question their own presuppositions.

It is of course sometimes possible that just by presenting ‘evidence’, you can convince a person that a particular scientific argument for creation makes sense ‘on the facts’. But usually, if that person then hears a different interpretation of the same evidence that seems better than yours, that person will swing away from your argument, thinking they have found ‘stronger facts’.

However, if you had helped the person to understand this issue of presuppositions, then they will be better able to recognize this for what it is—a different interpretation based on differing presuppositions—i.e. starting beliefs.

As a teacher, I found that whenever I taught the students what I thought were the ‘facts’ for creation, then their other teacher would just re-interpret the facts. The students would then come back to me saying, ‘Well sir, you need to try again.’

However, when I learned to teach my students how we interpret facts, and how interpretations are based on our presuppositions, then when the other teacher tried to reinterpret the facts, the students would challenge the teacher’s basic assumptions. Then it wasn’t the students who came back to me, but the other teacher! This teacher was upset with me because the students wouldn’t accept her interpretation of the evidence and challenged the very basis of her thinking.

What was happening was that I had learned to teach the students how to think rather than just what to think. What a difference that made to my class! I have been overjoyed to find, sometimes decades later, some of those students telling me how they became active, solid Christians as a result.

Debate Terms
If one agrees to a discussion without using the Bible as some people insist, then they have set the terms of the debate. In essence these terms are:

1.‘Facts’ are neutral. However, there are no such things as ‘brute facts’; all facts are interpreted. Once the Bible is eliminated in the argument, then the Christians’ presuppositions are gone, leaving them unable to effectively give an alternate interpretation of the facts. Their opponents then have the upper hand as they still have their presuppositions—see Naturalism, logic and reality.
2.Truth can/should be determined independent of God. However, the Bible states: ‘The fear of the Lord is the beginning of wisdom’ (Psalm 111:10); ‘The fear of the Lord is the beginning of knowledge’ (Proverbs 1:7). ‘But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; neither can he know them, because they are spiritually discerned’ (1 Corinthians 2:14).
A Christian cannot divorce the spiritual nature of the battle from the battle itself. A non-Christian is not neutral. The Bible makes this very clear: ‘The one who is not with Me is against Me, and the one who does not gather with Me scatters’ (Matthew 12:30); ‘And this is the condemnation, that the Light has come into the world, and men loved darkness rather than the Light, because their deeds were evil’ (John 3:19).

Agreeing to such terms of debate also implicitly accepts their proposition that the Bible’s account of the universe’s history is irrelevant to understanding that history!

Ultimately, God’s Word Convicts
1 Peter 3:15 and other passages make it clear we are to use every argument we can to convince people of the truth, and 2 Cor. 10:4–5 says we are to refute error (like Paul did in his ministry to the Gentiles). Nonetheless, we must never forget Hebrews 4:12: ‘For the word of God is living and powerful and sharper than any two-edged sword, piercing even to the dividing apart of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.’

Also, Isaiah 55:11: ‘So shall My word be, which goes out of My mouth; it shall not return to Me void, but it shall accomplish what I please, and it shall certainly do what I sent it to do.’

Even though our human arguments may be powerful, ultimately it is God’s Word that convicts and opens people to the truth. In all of our arguments, we must not divorce what we are saying from the Word that convicts.

Practical Application
When someone tells me they want ‘proof’ or ‘evidence’, not the Bible, my response is as follows:

‘You might not believe the Bible but I do. And I believe it gives me the right basis to understand this universe and correctly interpret the facts around me. I’m going to give you some examples of how building my thinking on the Bible explains the world and is not contradicted by science. For instance, the Bible states that God made distinct kinds of animals and plants. Let me show you what happens when I build my thinking on this presupposition. I will illustrate how processes such as natural selection, genetic drift, etc. can be explained and interpreted. You will see how the science of genetics makes sense based upon the Bible.’

One can of course do this with numerous scientific examples, showing how the issue of sin and judgment, for example, is relevant to geology and fossil evidence. And how the Fall of man, with the subsequent Curse on creation, makes sense of the evidence of harmful mutations, violence, and death.

Once I’ve explained some of this in detail, I then continue:

‘Now let me ask you to defend your position concerning these matters. Please show me how your way of thinking, based on your beliefs, makes sense of the same evidence. And I want you to point out where my science and logic are wrong.’

In arguing this way, a Christian is:

1.Using biblical presuppositions to build a way of thinking to interpret the evidence.
2.Showing that the Bible and science go hand in hand.1
3.Challenging the presuppositions of the other person (many are unaware they have these).
4.Forcing the debater to logically defend his position consistent with science and his own presuppositions (many will find that they cannot do this).
5.Honouring the Word of God that convicts the soul.
Remember, it’s no good convincing people to believe in creation, without also leading them to believe and trust in the Creator/Redeemer, Jesus Christ. God honours those who honour His Word. We need to use God-honouring ways of reaching people with the truth of what life is all about.

Naturalism, logic and reality
Those arguing against creation may not even be conscious of their most basic presupposition, one which excludes God a priori, namely naturalism/materialism (everything came from matter, there is no supernatural, no prior creative intelligence).2 The following two real-life examples highlight some problems with that assumption:

1.A young man approached me at a seminar and stated, ‘Well, I still believe in the big bang, and that we arrived here by chance random processes. I don’t believe in God.’ I answered him, ‘Well, then obviously your brain, and your thought processes, are also the product of randomness. So you don’t know whether it evolved the right way, or even what right would mean in that context. Young man, you don’t know if you’re making correct statements or even whether you’re asking me the right questions.’
The young man looked at me and blurted out, ‘What was that book you recommended?’ He finally realized that his belief undercut its own foundations—such ‘reasoning’ destroys the very basis for reason.

2.On another occasion, a man came to me after a seminar and said, ‘Actually, I’m an atheist. Because I don’t believe in God, I don’t believe in absolutes, so I recognize that I can’t even be sure of reality.’ I responded, ‘Then how do you know you’re really here making this statement?’ ‘Good point,’ he replied. ‘What point?’ I asked. The man looked at me, smiled, and said, ‘Maybe I should go home.’ I stated, ‘Maybe it won’t be there.’ ‘Good point,’ the man said. ‘What point?’ I replied.
This man certainly got the message. If there is no God, ultimately, philosophically, how can one talk about reality? How can one even rationally believe that there is such a thing as truth, let alone decide what it is?

Footnotes
1.In fact, science could avoid becoming still-born only in a Christian framework. Even secular philosophers of science are virtually unanimous on this. It required biblical presuppositions such as a real, objective universe, created by one Divine Lawgiver, who was neither fickle nor deceptive—and who also created the mind of man in a way that was in principle capable of understanding the universe. Back
2.This assumption is even defended, as a ‘practical necessity’ in discussing scientific things including origins, by some professing Christians who are evolutionists.
