Well, I don't know that we can say with CERTAINTY that life evolved but
people certainly do SAY it. I've heard calculations that to just form
one protein (amino acid?? I think) by chance, one of the building
blocks of life is 10 to the 46th power - and that's not even life. So the
probability for life is significantly greater than that. And the time
involved is significantly greater than the longest estimates for the age
of the earth - so what conclusions should you draw from this??
