I'll take a shot at this. There would be no problem getting me to abandon evolution. All it would take is evidence -- solid, verifiable evidence -- that the proliferation of species on earth did not appear in the sequence predicted by, and in a manner consistent with the theory. So far there is no such evidence. But I remain open-minded.
As for the literal, word-for-word accuracy of the creation account in Genesis, that's a far more difficult issue. I would have to be persuaded that most of what we know about astronomy, geology, and physics is wrong. I don't know what it would take to persuade me of that. I'm always open-minded to genuine evidence, but the task of overthrowing so many self-consistent, mutually consistent, and well-supported sciences seems very difficult.
I finally saw The Matrix this past weekend (rented it from NetFlix). Great movie. It really lived up to the hype.
