1. Nobody mentioned "theist" but you did mention that he must be atheist: which is wrong no matter how you translate it. "lacks belief in god or gods" is nothing like being a god and realising that. By introducing "theist" you are demoting God to a mortal underling, something new to this discussion. If God is God then, from his omniscience he knows who he is. Therefore he cannot "lack belief in god or gods". Unless you wish to dissect the word 'belief' ...which would be pedantic.
2. If the attributes of God are omniscient/potent/present where is there room for a superior to God?
