neither is true.

You know how the science teachers tell you that ALL scientist believe the Big Bang Theory made the world? Well no they actually do not believe in that. They believe that aliens created us. And why would they say they believed in the other? Because they dont want us people to freak out and if we would find out then there would be crime amongst us because people are "dumb" and would freak out like i said. So going back, we are like an "experiment" to them, they want to find out what is in our minds and how it actually works. We dont even know too and since they are waaaaay smarter than us... ._. So yes that is why they havnt taken over since they are much more powerful than us. And thats why we are abducted because they take feedback and study us. So aliens created us and someone else created them and it just keeps going but is there a stop?
