You could add to that only 14 of the 20 amino acids have ever been
synthesized under even strained plausible probiological conditions, and that
according to Gould, there must have been 10 times as many non proteinous
amino acids as proteinous ones. Figure the latter into your calculations,
the numbers go astronomical, figure the former in and they go to 0. Oh
yes, maybe the early proteins didn't use all 20 amino acids. Well, the only
problem with that is the 6 that have not been found in abiogenic experiments
are the ones most important for the properties of proteins. Am I getting
close to zero yet?
