My views go like this (I'm an Atheist so all you christians just stop reading now and start hating).
lets start with a recent poll, this poll asked many christians "if irrefutable evidence disproving god was presented to you tomorrow, would it change your religion?" a surprising(to me anyway) number of people, near 70%, said no, they would continue to believe.
This raises an interesting question, if god didnt exist, why would religion exist? why would so many people throughout history lie? I believe that God does not physically exist, neither do heaven or hell, or the garden of Eden, What we call God, What we call religion, is just a way to cope with the harsh nature of life. Some people would not be able to survive in this cruel world if they didnt believe that there was a chance of salvation, or that everything had already been planned. 
Religious people need religion just as much as us Athiests need science. In a way Science is just a religion based of fact instead of belief, I know that I am just as firm in my belief of science as many of my religious friends are in their belief in God. If everyone faced the truth and realized that there werent really answers in the bible, or in The Origin of Species, we could stop fighting about this, and start finding comfort in our fellow humans and be satisfied in the knowledge that no one will ever have all of the answers.
