Just because an idea is popular does not mean it is logical, true or helpful.
People used to believe the world was flat. Columbus was going to sail off the edge of the earth! People used to believe the earth was the center of the known universe, and that everything revolved around it.
The majority of Western society tolerated slavery, on the basis of the idea (taught in some churches, no less) that Africans were a lower form of humanity. That idea has been disproven and rejected.
Now as far as "God" is concerned, nobody on earth will be ever able to prove or disprove the existence of one. What this thread was about was the EFFECTS of belief (or lack thereof) in an unseen an unprovable entity.
I submit that the effects of belief in an unprobable entity lead to violent conflict, and a retardation of educational, scientific and political process.
