The best guess is that the “cosmos is all there is, was, or ever will be.” It may be a multiverse with billions and billions of universes. It could even be an infinite number of universes.
Since the Cosmos has always been and will always be, there is no need for a First Cause. And since evolution explains design in nature, there is no need for a Designer. Therefore there is no evidence for a creator God.
Before we had science to help us understand the universe, all we had to go by was ourselves. This is why we projected personality onto the natural forces of nature. Thunder was Thor’s hammer, and lightning was a bolt from Zeus.
So we created God in our image, we formed him after our likeness. He was a man because we were men. He was jealous because we were jealous. He was white because we were white. We even turned the brown Jesus into a white Jesus with blue eyes and blond hair. God didn’t create us, we created God.
