Of course. Hawking considered himself an atheist so he didn't believe in God as creator of time and space. He said, "if there were a God, which there isn’t. I’m an atheist.”

How can Penrose-Hawking provide a proof through science God exists and yet not be a theist?

As far as I can tell they claim the universe started spontaneously from nothing, which of course is false, since something can't come from nothing. That which does not exist can't cause anything. Nothing always comes from nothing. We exist, therefore, we are something.
