when you consider that the best minds of the last 150 years have been trying to prove or disprove it-- and the overwhelming response from all of the empirical evidence is that evolution is a fact.

the only reason we still call it a 'theory' is because you can't make it happen in a test tube... i mean, it's still open, so if there was something that disproved it, it would be considered. but nothing's popped up for the last 150 years... i can't be bothered reiterating what's in every science textbook ever written.
