one great proof is that he said that "he is always watching us"
meaning he is really keeping a good eye on us...
another thing, commonly stories during ancient times, the aliens are teaching us to do work.
well, isn't that what God had thought us? "to do the RIGHT THING!"
he also stated that there are heaven and hell! my depiction of this are...
Heaven: their home as they say "EDEN" of maybe "planet EDEN" where in you could do whatever you want and be happy if you did the good things!
Hell: scientifically maybe he has the "secret" technology in him that during those times he knew that the ground below us is very hot and has molten lavas
