"If everything must come from somewhere, where does God come from? Perhaps we don't need to explain where God comes from because God, unlike the universe, exists without any external cause. In that case, however, we've blatantly contradicted the very assumption that made us suppose that the universe must have been caused by God--namely, the assumption that everything must come from somewhere. Without that assumption, the existence of the universe is no longer evidence for God." Daniel Kolak and Raymond Martin, Wisdom Without Answers, (Belmont, CA: Wadsworth, 1998), p. 38-39.
