Before everything, even further back than science has proclaimed we had existed, was the Plane of Existence. Maybe you would think this plane would reside in a space? Maybe not. What is a space, anyway? Before everything had the chance to exist, there was just a lonely plane, stretching out infinitely, to an infinite horizon. Religion? Adam and Eve? None of these things ever existed, because there was no need for them to. All we had to believe in was the plane.
