God is border-guard between nothing and creation. In front of God is all creation, the cosmos. Behind God is nothingness, zero. (This is part of human conception of the Deity.) From nothing to something requires intelligence, logos. If zero is real number, then nothing is real concept. Yet nothing as absence, is impossible. Nothing can be imagined or thought, but not brought into being. To eliminate everything, including Himself, would be greatest accomplishment. Perhaps one could imagine God in parenthetical, dormant state while nothing reigns.
