Could Life Originate By Chance? by Nobody: 11:41pm On Jan 01, 2014
WHEN Charles Darwin advanced his theory of evolution he conceded that life may have been “originally breathed by the Creator into a few forms or into one.”1 But present-day evolutionary theory generally eliminates any mention of a Creator. Instead, the theory of the spontaneous generation of life, once repudiated, has been revived in a somewhat altered form.

2. Belief in a form of spontaneous generation can be traced back for centuries. In the 17th century C.E., even respected men of science, including Francis Bacon and William Harvey, accepted the theory. However, by the 19th century Louis Pasteur and other scientists had seemingly dealt it a deathblow, having proved by experiments that life comes only from previous life. Nevertheless, out of necessity, evolutionary theory assumes that long ago microscopic life must somehow have arisen spontaneously from nonliving matter.

A New Form of Spontaneous Generation

3 A current evolutionary position on life’s starting point is summarized in his book, The Selfish Gene, by Richard Dawkins. He speculates that in the beginning, Earth had an atmosphere composed of carbon dioxide, methane, ammonia and water. Through energy supplied by sunlight, and perhaps by lightning and exploding volcanoes, these simple compounds were broken apart and then they re-formed into amino acids. A variety of these gradually accumulated in the sea and combined into proteinlike compounds. Ultimately, he says, the ocean became an “organic soup,” but still lifeless.

4 Then, according to Dawkins’ description, “a particularly remarkable molecule was formed by accident”—a molecule that had the ability to reproduce itself. Though admitting that such an accident was exceedingly improbable, he maintains that it must nevertheless have happened. Similar molecules clustered together, and then, again by an exceedingly improbable accident, they wrapped a protective barrier of other protein molecules around themselves as a membrane. Thus, it is claimed, the first living cell generated itself.

5 At this point a reader may begin to understand Dawkins’ comment in the preface to his book: “This book should be read almost as though it were science fiction.” But readers on the subject will find that his approach is not unique. Most other books on evolution also skim over the staggering problem of explaining the emergence of life from nonliving matter. Thus Professor William Thorpe of the zoology department of Cambridge University told fellow scientists: “All the facile speculations and discussions published during the last ten to fifteen years explaining the mode of origin of life have been shown to be far too simple-minded and to bear very little weight. The problem in fact seems as far from solution as it ever was.”

6 The recent explosive increase of knowledge has only served to magnify the gulf between nonliving and living things. Even the oldest known single-celled organisms have been found to be incomprehensibly complex. “The problem for biology is to reach a simple beginning,” say astronomers Fred Hoyle and Chandra Wickramasinghe. “Fossil residues of ancient life-forms discovered in the rocks do not reveal a simple beginning. . . . so the evolutionary theory lacks a proper foundation.”5 And as information increases, the harder it becomes to explain how microscopic forms of life that are so incredibly complex could have arisen by chance.

7 The principal steps en route to the origin of life, as envisioned by evolutionary theory, are (1) the existence of the right primitive atmosphere and (2) a concentration in the oceans of an organic soup of “simple” molecules necessary for life. (3) From these come proteins and nucleotides (complex chemical compounds) that (4) combine and acquire a membrane, and thereafter (5) they develop a genetic code and start making copies of themselves. Are these steps in accord with the available facts?

The Primitive Atmosphere

8 In 1953 Stanley Miller passed an electric spark through an “atmosphere” of hydrogen, methane, ammonia and water vapor. This produced some of the many amino acids that exist and that are the building blocks of proteins. However, he got just 4 of the 20 amino acids needed for life to exist. More than 30 years later, scientists were still unable experimentally to produce all the 20 necessary amino acids under conditions that could be considered plausible.

9 Miller assumed that earth’s primitive atmosphere was similar to the one in his experimental flask. Why? Because, as he and a co-worker later said: “The synthesis of compounds of biological interest takes place only under reducing [no free oxygen in the atmosphere] conditions.”6 Yet other evolutionists theorize that oxygen was present. The dilemma this creates for evolution is expressed by Hitching: “With oxygen in the air, the first amino acid would never have got started; without oxygen, it would have been wiped out by cosmic rays.”7
10 The fact is, any attempt to establish the nature of earth’s primitive atmosphere can only be based on guesswork or assumption. No one knows for sure what it was like.

Would an “Organic Soup” Form?

11 How likely is it that the amino acids thought to have formed in the atmosphere would drift down and form an “organic soup” in the oceans? Not likely at all. The same energy that would split the simple compounds in the atmosphere would even more quickly decompose any complex amino acids that formed. Interestingly, in his experiment of passing an electric spark through an “atmosphere,” Miller saved the four amino acids he got only because he removed them from the area of the spark. Had he left them there, the spark would have decomposed them.

12 However, if it is assumed that amino acids somehow reached the oceans and were protected from the destructive ultraviolet radiation in the atmosphere, what then? Hitching explained: “Beneath the surface of the water there would not be enough energy to activate further chemical reactions; water in any case inhibits the growth of more complex molecules.”

13 So once amino acids are in the water, they must get out of it if they are to form larger molecules and evolve toward becoming proteins useful for the formation of life. But once they get out of the water, they are in the destructive ultraviolet light again! “In other words,” Hitching says, “the theoretical chances of getting through even this first and relatively easy stage [getting amino acids] in the evolution of life are forbidding.”9
14 Although it commonly is asserted that life spontaneously arose in the oceans, bodies of water simply are not conducive to the necessary chemistry. Chemist Richard Dickerson explains: “It is therefore hard to see how polymerization [linking together smaller molecules to form bigger ones] could have proceeded in the aqueous environment of the primitive ocean, since the presence of water favors depolymerization [breaking up big molecules into simpler ones] rather than polymerization.”10 Biochemist George Wald agrees with this view, stating: “Spontaneous dissolution is much more probable, and hence proceeds much more rapidly, than spontaneous synthesis.” This means there would be no accumulation of organic soup! Wald believes this to be “the most stubborn problem that confronts us [evolutionists].”

15 There is, however, another stubborn problem that confronts evolutionary theory. Remember, there are over 100 amino acids, but only 20 are needed for life’s proteins. Moreover, they come in two shapes: Some of the molecules are “right-handed” and others are “left-handed.” Should they be formed at random, as in a theoretical organic soup, it is most likely that half would be right-handed and half left-handed. And there is no known reason why either shape should be preferred in living things. Yet, of the 20 amino acids used in producing life’s proteins, all are left-handed!

16 How is it that, at random, only the specifically required kinds would be united in the soup? Physicist J. D. Bernal acknowledges: “It must be admitted that the explanation . . . still remains one of the most difficult parts of the structural aspects of life to explain.” He concluded: “We may never be able to explain it.”

Probability and Spontaneous Proteins

17 What chance is there that the correct amino acids would come together to form a protein molecule? It could be likened to having a big, thoroughly mixed pile containing equal numbers of red beans and white beans. There are also over 100 different varieties of beans. Now, if you plunged a scoop into this pile, what do you think you would get? To get the beans that represent the basic components of a protein, you would have to scoop up only red ones—no white ones at all! Also, your scoop must contain only 20 varieties of the red beans, and each one must be in a specific, preassigned place in the scoop. In the world of protein, a single mistake in any one of these requirements would cause the protein that is produced to fail to function properly. Would any amount of stirring and scooping in our hypothetical bean pile have given the right combination? No. Then how would it have been possible in the hypothetical organic soup?

18 The proteins needed for life have very complex molecules. What is the chance of even a simple protein molecule forming at random in an organic soup? Evolutionists acknowledge it to be only one in 10113 (1 followed by 113 zeros). But any event that has one chance in just 1050 is dismissed by mathematicians as never happening. An idea of the odds, or probability, involved is seen in the fact that the number 10113 is larger than the estimated total number of all the atoms in the universe!

19 Some proteins serve as structural materials and others as enzymes. The latter speed up needed chemical reactions in the cell. Without such help, the cell would die. Not just a few, but 2,000 proteins serving as enzymes are needed for the cell’s activity. What are the chances of obtaining all of these at random? One chance in 1040,000! “An outrageously small probability,” Hoyle asserts, “that could not be faced even if the whole universe consisted of organic soup.” He adds: “If one is not prejudiced either by social beliefs or by a scientific training into the conviction that life originated [spontaneously] on the Earth, this simple calculation wipes the idea entirely out of court.”

20 However, the chances actually are far fewer than this “outrageously small” figure indicates. There must be a membrane enclosing the cell. But this membrane is extremely complex, made up of protein, sugar and fat molecules. As evolutionist Leslie Orgel writes: “Modern cell membranes include channels and pumps which specifically control the influx and efflux of nutrients, waste products, metal ions and so on. These specialised channels involve highly specific proteins, molecules that could not have been present at the very beginning of the evolution of life.”

The Remarkable Genetic Code

21 More difficult to obtain than these are nucleotides, the structural units of DNA, which bears the genetic code. Five histones are involved in DNA (histones are thought to be involved in governing the activity of genes). The chance of forming even the simplest of these histones is said to be one in 20100—another huge number “larger than the total of all the atoms in all the stars and galaxies visible in the largest astronomical telescopes.”

22 Yet greater difficulties for evolutionary theory involve the origin of the complete genetic code—a requirement for cell reproduction. The old puzzle of ‘the chicken or the egg’ rears its head relative to proteins and DNA. Hitching says: “Proteins depend on DNA for their formation. But DNA cannot form without pre-existing protein.” This leaves the paradox Dickerson raises: “Which came first,” the protein or the DNA? He asserts: “The answer must be, ‘They developed in parallel.’” In effect, he is saying that ‘the chicken’ and ‘the egg’ must have evolved simultaneously, neither one coming from the other. Does this strike you as reasonable? A science writer sums it up: “The origin of the genetic code poses a massive chicken-and-egg problem that remains, at present, completely scrambled.”

23 Chemist Dickerson also made this interesting comment: “The evolution of the genetic machinery is the step for which there are no laboratory models; hence one can speculate endlessly, unfettered by inconvenient facts.” But is it good scientific procedure to brush aside the avalanches of “inconvenient facts” so easily? Leslie Orgel calls the existence of the genetic code “the most baffling aspect of the problem of the origins of life.” And Francis Crick concluded: “In spite of the genetic code being almost universal, the mechanism necessary to embody it is far too complex to have arisen in one blow.”

24 Evolutionary theory attempts to eliminate the need for the impossible to be accomplished “in one blow” by espousing a step-by-step process by which natural selection could do its work gradually. However, without the genetic code to begin reproduction, there can be no material for natural selection to select.

Amazing Photosynthesis

25 An additional hurdle for evolutionary theory now arises. Somewhere along the line the primitive cell had to devise something that revolutionized life on earth—photosynthesis. This process, by which plants take in carbon dioxide and give off oxygen, is not yet completely understood by scientists. It is, as biologist F. W. Went states, “a process that no one has yet been able to reproduce in a test tube.”22 Yet, by chance, a tiny simple cell is thought to have originated it.

26 This process of photosynthesis turned an atmosphere that contained no free oxygen into one in which one molecule out of every five is oxygen. As a result, animals could breathe oxygen and live, and an ozone layer could form to protect all life from the damaging effects of ultraviolet radiation. Could this remarkable array of circumstances be accounted for simply by random chance?

Is Intelligence Involved?

27 When confronted with the astronomical odds against a living cell forming by chance, some evolutionists feel forced to back away. For example, the authors of Evolution From Space (Hoyle and Wickramasinghe) give up, saying: “These issues are too complex to set numbers to.” They add: “There is no way . . . in which we can simply get by with a bigger and better organic soup, as we ourselves hoped might be possible a year or two ago. The numbers we calculated above are essentially just as unfaceable for a universal soup as for a terrestrial one.”

28 Hence, after acknowledging that intelligence must somehow have been involved in bringing life into existence, the authors continue: “Indeed, such a theory is so obvious that one wonders why it is not widely accepted as being self-evident. The reasons are psychological rather than scientific.” Thus an observer might conclude that a “psychological” barrier is the only plausible explanation as to why most evolutionists cling to a chance origin for life and reject any “design or purpose or directedness,” as Dawkins expressed it. Indeed, even Hoyle and Wickramasinghe, after acknowledging the need for intelligence, say that they do not believe a personal Creator is responsible for the origin of life.26 In their thinking, intelligence is mandatory, but a Creator is unacceptable. Do you find that contradictory?

Is It Scientific?

29 If a spontaneous beginning for life is to be accepted as scientific fact, it should be established by the scientific method. This has been described as follows: Observe what happens; based on those observations, form a theory as to what may be true; test the theory by further observations and by experiments; and watch to see if the predictions based on the theory are fulfilled.

30 In an attempt to apply the scientific method, it has not been possible to observe the spontaneous generation of life. There is no evidence that it is happening now, and of course no human observer was around when evolutionists say it was happening. No theory concerning it has been verified by observation. Laboratory experiments have failed to repeat it. Predictions based on the theory have not been fulfilled. With such an inability to apply the scientific method, is it honest science to elevate such a theory to the level of fact?

31 On the other hand, there is ample evidence to support the conclusion that the spontaneous generation of life from nonliving matter is not possible. “One has only to contemplate the magnitude of this task,” Professor Wald of Harvard University acknowledges, “to concede that the spontaneous generation of a living organism is impossible.” But what does this proponent of evolution actually believe? He answers: “Yet here we are—as a result, I believe, of spontaneous generation.”27 Does that sound like objective science?

32 British biologist Joseph Henry Woodger characterized such reasoning as “simple dogmatism—asserting that what you want to believe did in fact happen.” How have scientists come to accept in their own minds this apparent violation of the scientific method? The well-known evolutionist Loren Eiseley conceded: “After having chided the theologian for his reliance on myth and miracle, science found itself in the unenviable position of having to create a mythology of its own: namely, the assumption that what, after long effort, could not be proved to take place today had, in truth, taken place in the primeval past.”

33 Based on the evidence, the spontaneous generation of life theory appears better to fit the realm of science fiction than scientific fact. Many supporters apparently have forsaken the scientific method in such matters in order to believe what they want to believe. In spite of the overwhelming odds against life originating by chance, unyielding dogmatism prevails rather than the caution normally signaled by the scientific method.

Not All Scientists Accept It

34 Not all scientists, however, have closed the door on the alternative. For example, physicist H. S. Lipson, realizing the odds against a spontaneous origin for life, said: “The only acceptable explanation is creation. I know that this is anathema to physicists, as indeed it is to me, but we must not reject a theory that we do not like if the experimental evidence supports it.” He further observed that after Darwin’s book, The Origin of Species, “evolution became in a sense a scientific religion; almost all scientists have accepted it and many are prepared to ‘bend’ their observations to fit in with it.”30 A sad but true commentary.

35 Chandra Wickramasinghe, professor at University College, Cardiff, said: “From my earliest training as a scientist I was very strongly brainwashed to believe that science cannot be consistent with any kind of deliberate creation. That notion has had to be very painfully shed. I am quite uncomfortable in the situation, the state of mind I now find myself in. But there is no logical way out of it. . . . For life to have been a chemical accident on earth is like looking for a particular grain of sand on all the beaches in all the planets in the universe—and finding it.” In other words, it is just not possible that life could have originated from a chemical accident. So Wickramasinghe concludes: “There is no other way in which we can understand the precise ordering of the chemicals of life except to invoke the creations on a cosmic scale.”
