I like this guy, he's got a good scence of humor.
He does however come to all his conclusions from an assumption that God is a myth or fairy tale.
Equations based on assumptions are very dangerous.
The is a ton of evidence to suggest God exists, yet no one has ever come close to proving that He does not exist.
You go through every statement he makes in that film knowing that the evidence points to there being a God (and there is absolutely no evidence to God being a fairy tale) and all of a sudden his intelligent well thought out critiques sound foolish.
