The only time I hear this line of questioning come up is when theists claim that since everything has to come from something, god must exist to have created the universe. However, by their own logic, that means god himself must have his own creator.... and that creator has its own creator and there has to be a creator for hat creator and so on. If God doesn't need a creator, the line of logic that the theist was on just disolves.
