The universe was created somehow, one of the terms used to describe our complete lack of undersrtanding about how and why we exist is God.
Neither science or religion can explain how something can be made from nothing, i.e if God made the universe; who made god. Where did the energy come from that created the big bang, how was the vessel that contained the energy formed etc etc.

If/when we ever find out how you can make something from literally nothing we will have the answer.

Great debate but totally mindfucking as neither side has fuck all answers to the big questions we really want the answers to.
