The scientific theory that invalidated atheism long ago. The Big Bang theory affirms what religions teach by providing evidence for a beginning of the universe. According to the scientific principle of causality, it had to proceed from something and it's a lot more logical to believe that it proceeded from an intelligent mind (which would account for the mechanisms of the universe, its mathematical cosmology and the fine-tuning) because you don't get something from nothing.

Contrary to popular opinion, The Big Bang theory simply describes the moments after the universe begun.
