The Fermi Paradox asked why we hadn’t been Contacted.  Some said that we had.  Most of our older religions worshiped beings of great power that came from the sky.  We called them gods.  The worship of the gods, God, or even no God at all has dominated the path of our history.  Civilizations have risen and fallen based on their beliefs, and few differences of opinion have been so explosive.  Did we make them up, are they real, or were they simply aliens making Contact?
