Is it possible that God is actually an alien being?

And Heaven is an actual planet or solar system somewhere in the universe? And these alien beings are so far advanced that their abilities are far beyond our comprehension? That earth was populated by that culture in their image and angels are actually the names of those beings who are sent here to observe and look over us? That alien life that's been doented in ufo sightings are those entities that come back to somehow extract the souls of the dead and take them back to where they come from? That everything that the bible tells of is due to actual events committed by alien life? Any plausibility to this theory?
