It's a question we got from theists, who insist everything must have a creator. We're just throwing it back at you.Asking the question 'Who created God?' is nonsensical because we humans cannot
imagine anything outside of time and space, let alone God. People often feel that's a
clever question.
If an extant universe must needs have a creator, ergo: God; why is asking the same question about a presumed god nonsensical?
How the universe came to be is a question for theoretical physics. Positing a god explains nothing, it's a claim of agency, not mechanism; who not how. God's mechanism remains unexplained.EITHER the universe created itself when it didn't exist (ie no physics, no mathematics,
no space etc..) or it was created by an external agency.
