>Its meaningful to concede that the theory of evolution isn't the equivalent of a mathematical proof.

This is your straw man argument, which you've been trying to beat. No-one has been claiming that theory of evolution is a equivalent of mathematical proof. Mathematics is based on a set of definitions that have no connection to reality(in a sense that it does not depend on reality), that makes it exact on its own. Science will never achieve that we're fine with it. We live in a world of assumptions, which allows us to map reality that we don't directly perceive at the moment.
