His considered answer to what God was doing before creating the universe was "the world was made with time and not in time." Augustine's God is a being who transcends time, a being located outside time altogether and responsible for creating time as well as space and matter. Thus Augustine skillfully avoided the problem of why the creation happened at that moment rather than some earlier moment. Identical reasoning applies to the scientific problem. If the universe originated in time, then it cannot have been caused by any physical process that has a finite probability, because if it did, then the event would already have happened, an infinite time ago. ...He wasn't even the first person to hit on the idea of time coming into being with the universe. Plato said much the same thing hundreds of years earlier. The history of philosophy is so rich and diverse that it would be astonishing if theories emerging from science hadn't been foreshadowed in some vague way by somebody.
