Pat, you are, of course, correct. If the strict sense all scientific knowledge is provisional, which is the beautiful thing about it.
The distinction I was trying to make is that evolution happened, and is happening. There is no theory that will come along and completely disprove evolution, especially in the creationism sense. It is possible the copious amount of evidence for evolution will be integrated into a larger, more comprehensive theory at some point (as Newtonian mechanics was absorbed into Relativity and Quantum Mechanics).
Many religious apologists like to try to use ‘theory’ in the colloquial sense to indicate that it’s just some guys opinion, which it is not.
DKV, if you are really asking this to gain knowledge, I’d look up the reference I quoted. I don’t have the interest or time to get into a detailed discussion on evolution, especially on a woodworking site.
