I love these kind of informative videos, thank you and thank you YouTube. I dont even watch TV anymore, I find all my entertainment on YouTube. I dont understand how a creationist can still be a creationist after watching this sort of video. Yes, all you creationists, there is science behind refuting creationism. You should also watch one on evolution while your at it.
