Why do you think religion exists?

In my opinion, I think God was first conceived because of our burning desire to explain things. I think that people still believe in God now because of the human need to connect with someone. We can not connect with other people, other than through the manipulation of the physics world (talking, touching, etc) but our consciousness is still all alone. With God we can connect consciousnesses, the ultimate togetherness.

What do you guys think? Or if you believe in God, why?
