Is there a God? · Question 3
Then who made God? Isn't that dodging the question?

A child asks: “If God made everything, who made God?”
The answer: Christians do not say “everything that exists was made by someone.” They say that whatever came to be, or exists by leaning on something else, needs an explanation. God is not one more object that appeared inside the universe, but the source of existence, with no beginning and nothing to lean on.
If God too had been made by someone, that maker would have to be the more basic explanation, and the question would never end. Of course this alone does not complete a proof that God is real. What it does show is that “who made God?” misplaces the God Catholics speak of, asking about him as if he were one of the creatures.
An analogy — a story and its author
A character in a fairy tale can search every scene in the book and never turn up the author as another character, because the author does not exist in the story the way the characters do. Of course an author is not exactly like God either. This analogy tells us only that we must not go looking for the Creator among the creatures.
Briefly: “God isn't the first of the made things. God is the beginningless source that lets every made thing exist.”
