I don't know what you mean by "agree with" or "have a scientific basis." Are you asking if I think one of them is correct? I don't think Coyoteman was presenting them as the complete range of choices, one of which has to be correct. But it's hard to argue with "Any method other than the four described above."
It sounds almost like you're asking if I believe there's such a thing as "the first life forms."
So then do you reject the other 4 hypotheses?
