What if the aliens where the rulers and creators of the earth and its inhabitants? What if we were an experiment that went bad and they have been trying to extinguish, or simply content watching their craft. What if!

I watched something like that on history channel. And they had really amazing evidence to prove it.
Another question is ''what if aliens are evolved humans from the future?''

Beware of theists though, they claim ufo's are angels and demons lol... If anything amazes me, its human stupidity.
