We all have beliefs, it's impossible to not have any, some people believe a superior entity is responsible for our universe... and some people believe the universe pretty much blew up into existence.
I believe in God and I don't think it's for simple minded individuals, it's hard to maintain a constant belief in something that is super hard to believe in.
(although some religious people ARE simple minded individuals, but that has no corelation with their beliefs. ex. the folks over at Westboro Baptist Church, or the athiests claiming to be conducting the crusade against religion.)
