Let me try elaborating a little on Bill's post. This is not a case where
the "phenonema unaccounted for in the model" represent the "let's wait
for the advancement of science" argument. The "phenonema unaccounted for
in the model" are known phenomena, basic things such as, for example,
chemistry ;-). People seem to keep forgetting that there are many models
for abiogenesis. The probability calculations deal with only one of these,
the spontaneous origin of something like a protein or whatever purely
by chance in some primeval goo. This model has not been seriously
considered by people working in the field for thirty years. Why? Because
its so darned unlikely ;-). Thus, your reply to Bill's first point:

"I agree, but the more highly improbably, the less one
ought to hitch one's wagon to it as a plausible
explanation, don't you think?" -- Jim

Is right on the mark, that's why few are hitching their wagons to
to this explanation.

Anyway, to conclude, it seems rather odd to be talking about dealing
blows to an idea that's been dead for thirty years.
