It isn't a fact, per se, but a theory. But then again, creationism is also a theory. It goes back to the phrase, Did God create man or did man invent God? and right now, we can't be completely sure either way. I tend to lean more toward evolution, although I do believe God. I just think we shouldn't think of the Bible as a historical text, because it clearly isn't. The Bible dates the earth to be around 6,000 years old, whereas carbon testing can date the world to billions of years old.
