Believe it or not (see what I did there? ) our human minds seemingly demand explanations for everything (especially our origins). Some people do that by throwing in a creator, who hit the first domino, so to speak. People like Chef, you, and I squelch this demand, and are satisfied with an "I don't know" when it comes to the beginning of the universe.
However, when people make the leap of faith (thanks, Kierkegaard), I do not believe that they are "weak" or "stupid." To me, they are simply fulfilling another demand (although it may be comparatively minor) made by their brain. Perhaps this fulfilling of the demand is one of the reasons why religious people tend to be happier than non-religious people.
