Homo est Deus
Man is insecure, he needs to believe there's a great power out there that looks after him and gives him strenght, thus, he created God.
God exists, he/she is real for everyone who believes in It. There isn't an absolute God, there's as many gods as there are believers, every man and woman is their own God.
As for religion, I can't honestly say anything nice about any out there. Men have done so many horrible things in the name of God and religion, and there's still many science developments being halted or delayed because they are considered sacrilege by the church. Men really need to stop considering religion an authority if we want, as species, to evolve.
That's just my point of view.
