While 'extraterrestrial' is an adequate term for 'aliens', it barely points in the right direction.
Consider physics, history, archeology, Biblical and extra-Biblical accounts. Consider quantum physics and greater dimensions. Watch the movie 'Flatland' to understand the physics of Jesus's resurrection.
Watch this nearly one-hour clip with Steve Quayle and Timothy Alberino to gain a deeper understanding.
Oh, and dump the TV. It IS one of the single greatest manipulation/indoctrination tools in plain sight.
