“Why is it that virtually EVERYBODY thinks that if there are Space Aliens, ETs or some kind of Space Travelers, they would have some superior intelligence relative to us ?”
Just two reasons,
1.They figured out how to get here.
2.They are smart enough not to have anything to do with us.
What if they are not from space? Maybe they are time machines from the future? Or from new dememtions? Or maybe from the Inner World? From a Nazi base at the south pole?
