If evolution were debunked, it would be by a scientific theory [ What's a Scientific Theory?] that: (a) explains the evidence better than evolution does; (b) explains additional phenomena that evolution can't explain; and (c) is consistent with all other branches of science. So far, because all the evidence yet discovered fits into and supports the theory of evolution, there's nothing on the horizon that can do the job. But scientists are open-minded.

I understand your posting and feelings regarding the scientific nature regarding evolution...but that was not my point...my point was that should evolution be debunked either by better theory OR Deux Ex Machina revelation that science would not totally crumble...evolution is not a foundational science the way math,physics, geology, and chemistry our as examples. I don't think Creationists are going to picket a high school chemistry class!
