I respectfully refer the group, once again, to Barricelli's symbioorganisms. Self-replicating computer programs evolving by random mutation and natural selection, and now exactly 40 years old.
Yes, computer programs can completely create random mutation and natural selection, but those programs, such as Barricelli's symbioorganisms, are programs created by intelligent intervention (in this case, Barricelli), not unaided, natural processes.
In fact, as I pointed out above, computer programs can do a bang-up job of creating genetic algorithms, and that fact is not in dispute. Rather, what is missing is how (or evidence of) a program gets created without intelligent intervention (after all, a lifeless, unintelligent planet would have no intelligent means other than random self-forming events to create life and intelligence).
