The renowned atheist of the latter 20th century, Dr. Carl Sagan, estimated that the mathematical probability of the simplest form of life emerging from non-living matter has the unbelievable odds of one chance in 10 to the two billionth power (10^2,000,000,000 which is a 10 followed by two billion zeroes). The enormity of this figure is revealed by the fact that it would take 6,000 books of 300 pages each just to write the number !! (11) So how could an event with a probability of 1 in 10 with two billion zeroes after it ever happen? It is absolutely, mathematically impossible.
Of course, Sagan still believed it happened. He had no choice since he consciously refused to accept even the possibility of a Creator.
Evolutionists claim the earth is about five billion years old and the universe 10 to 20 billion years old. There are about 10^18 seconds in 20 billion years. Therefore, even if a trial and error combination occurred every second for 20 billion years, the odds still appear hopelessly high against the natural assembly of even a single molecule.
Stuart Kauffman, in his book Investigations (12), considers the number of possible proteins of length 200 and the maximum number of pairwise collisions of particles throughout the history of the universe. Kauffman concluded that the known universe hasn’t had time since the big bang to run through all possible proteins of length 200 even once. To emphasize this point, he notes it would take more than 10^67 times the current [accepted] time span of the universe to construct all possible proteins of length 200 even once.(13) And that is just proteins composed of 200 amino acids, not even close to what would be required in the simplest theoretical cell.
As the facts intrude on the evolutionists’ worldview, they have offered lame explanations that are impregnable to attack. They claim there are innumerable other possible life forms unlike any life we know of—there are other possible proteins, other possible arrangements, other possible simpler organizations suitable for life.(14,15) Evolutionists use the same basic argument for biomolecules, life, the Earth, and the universe itself. When a design is too improbable to form by chance, they claim there are an infinitude of other biomolecules, other life forms, other planets, or other universes unlike ours. Their desperation is obvious.
