I am of the opinion that this universe is a procedurally-generated simulation of a universe created by an intelligence of some sort in another universe, which is, in itself, a simulation, and so on, like turtles, all the way out to one original universe, which is probably more easily explicable according to whatever laws of physics govern it, those being entirely different from our own.

If anybody is interested, I can demonstrate how this theory answers several of the remaining unanswered questions of existence and metaphysics.
