I haven't watched the video (I'm at work) but as a former Christian now turned atheist, I can tell you that when you grow up hearing that evolution is a 'diabolical conspiracy from the pit of hell', it's not very easy to question.

I remember one night, looking up at the stars and rejoicing that Einstein, in all his genius, never got the 'truths' that the Bible taught me. So a part of it is feeling smug that you know something that 'these intellectuals' don't know.
