"Theories" are as good as facts in science. Theories come about when an hypothesis is so well established, tested, and proven that it graduates to the level of 'Theory'. I'm not getting philosophical with discussing "absolute truth". I'm saying based on everything we know, right now, evolution is the ONLY thing that makes sense. It is not a religion, it has not been debunked, it's proven to such a degree that I'd wage my house on it never being debunked. I don't claim to be an expert, but I do know a great deal about it.
