I do wonder what a scientific fact is.....and how they proved that creationism isn't a fact.  I might not believe in it, but I can't prove that it is wrong.

Oh creationism is provably wrong by any normal use of the word proof. I mean, if you are the sort of person who says that you can't prove that there was a Tsunami in Japan the other week, you'd be right by some ridiculous standards of proof (we might all be having some mass hallucination), but by any reasonable standard of proof Creationism is disproved. Itelligent Design is also so bereft of factual evidence to support it, and so outweighed by evidence which contradicts it, that it is disproven to the standard required by any court.
