Nothing is absolute by the terms of proof with which you seem to think are necessary. Except of course that your terms only apply to evolutionary theory.

No one has argued that evolution is 100% perfect and we know exactly how we got from the first life form to every life form on the planet now except in the general sense. Is there room for a creator, or extraterrestrial influence or whatever in there? Sure, but it isn't a useful line of questioning.

If, instead you research how stuff evolves and happen upon a case where something evolved in a way that is completely impossible given the understanding of evolution, then you have to either modify your understanding and see if it still works, or you've come across something truly unexplainable by nature. Then you've proven God (or something like it) exists!

Unfortunately all evidence points to the Universe being internally self-consistent. That isn't to say that means there is no God. It's just saying that when stuff happens, it's not magic, it's because the laws of nature make/allow it to happen.

You aren't trying to argue some common sense point that the rest of us are being bullheaded about. You're trying to hold a rigorously tested theory to a ridiculous standard of proof that nothing can satisfy and simultaneously claiming other things do satisfy it.

If you were instead saying that the Pythagorean theorem wasn't complete because every possible right triangle hadn't been tested to see if a^2 + b^2 = c^2, and we'd be saying, look here there is mathematical proofs, and you'd say, but you don't know that it's always been true because you haven't been alive forever and observed every single right triangle ever in existence. Seriously. Just stop.
