The question to your answer is given by an "enlightened" dutch person. He is also known in the USA and in Asia aswell I even think. His name is Han Marie Stiekema.
He says that also God is a creation that comes from "The Great Vacuum" where all existence gets created from, moment to moment. How it exactly works I can not tell ofcourse, but I think it's interesting to ponder about, even though it is futile
.
Maybe God is "All that is" and the Vacuum is "All that is not"?
