"I've refuted Darwinism countless times by undermining its requisite presuppositions: one cannot begin without presupposing God because one is then faced with the absurdity of assuming transcendental truth stands on its own. Truths like the Pythagorean Theorem stand on their own. They are, as it were, the great 'I AM'."
A philosophical assertion with no evidence? Wow, why am I reminded of the Greeks? Oh, that's right. Greek scientists thought too much about constructing logical arguments for observed phenomena that they forgot to go out and actually, well, *investigate* them.
Everything you've said assumes a basis for truth ascertained by investigation. Darwinistic presuppositions assume truth and falshood but is utterly impotent to account for its underlying basis - some absolute standard of truth. It must presuppose it as though it stood on its own. The Creationist OTOH presupposes God and is able to account for truth because he has a single, unified, rational starting point.
