God or no God? Answer ...God
Why? I simply cannot accept that the incredible complexity of life originated by chance. The odds of a single functional protein developing are mind boggling. Walter Bradley and Charles Thaxton (authors of The Mystery of Life's Origins: Reassessing Current Theories) had this to say about probability and the origin of a protein after outlining a number of arguments against an evolutionary origin of the same:
To simplify the problem, one may assume the probability of getting an L-amino acid (versus a D-amino acid) to be 50 percent and the probability of joining two such amino acids with a peptide bond to also be 50 percent. The probability of getting the right amino acid in a particular position may be assumed to be 5 percent, assuming equal concentration of all twenty amino acids in the pre biotic soup. The first two assumptions are realistic, while the third would be too low for some amino acids and to high for others.
Neglecting the problem of reactions with non-amino acid chemical species, the probability of getting everything right in placing one amino acid would be 0.5 x 0.5 x .05 = .0125. The probability of properly assembling N such amino acids would be .0125 x .0125 x ...continued for N terms of .0125. If a functional protein had one hundred active sights, the probability of getting a proper assembly would be .0125 multiplied times itself one hundred times, or 4.9 x 10 191 . Such improbabilities have led essentially all scientists who work in the field to reject random, accidental assembly or fortuitous good luck as an explanation for how life began.
If we assume that all carbon on earth exists in the form of amino acids and that amino acids are allowed to chemically react at the maximum possible rate of 10 12 /s for one billion years (the greatest possible time between the cooling of the earth and the appearance of life), we must still conclude that it is incredibly improbable (~10 65 ) that even one functional protein would be made, as H.P. Yockey has pointed out. (H.P. Yockey, "A Calculation of the Probability of Spontaneous Biogenesis by Information Theory,"Journal of Theoretical Biology 67(1981):377)
D.Kenyon and G.Steinman and Sir Fredrick Hoyle come to similar conclusions, with the latter commenting, "The current scenario of the origin of life is about as likely as the assemblage of a 747 by a tornado whirling through a junkyard."(F. Hoyle, The Intelligent Universe, 1983)
