You are right, it is an interesting read. I find it interesting how few people have actually read Darwin and what he proposed in his works.
As for us evolving a need for religion, why?
Evolution supposedly selects for survival traits, what survival trait is there that supports a need to believe in religion? Perhaps it is the actual existance of God?
As for the evidence that proves there is no G/god, perhaps you ought to examine it, you might be surprised at the acarcity of it in light of current scientific knowledge.
