There you go, the hole in the wall. You have none at all. Unless you define it to be. Where your definition is nothing more or less than someone elses definition that there must be a God. So you're back at square 1. Do not pass Go.

@MrWiggles: The universe as we understand it now, is VERY random. It just evens out nicely due to statistics. For instance, at any point (ANY point and ANY time, where point is probably as small as planck-space), two particles may appear out of nowhere, only to disappear again by interacting by the two particles from the point right next to them. How do we know? Zero-point energy and black-hole radiation that skew the symmetry. It's very random indeed.
