Theory: there is no such thing as aliens. They’re actually evolved humans. Or more specifically, Ancient Egyptians. Think about it, the work the Egyptians did and their expert craftsmanship is impossible without technology. But technology didn’t exist back then. My theory is that the ancient Egyptians actually had more evolved technology than we do today. They were smarter than us and even figured out how to fly. But it was only available for the rich. Eventually the Egyptians went to space! The rich left earth completely and never came back. They used technology and evolved as people. They could’ve hid their traces or there’s something maybe a temple that we still haven’t found showing what happened. I mean the Egyptians are one of the most mysterious civilizations in the world! Who knows what happened. The Ancient Egyptians are what we now call Aliens. But that’s just a theory… A HISTORY THEORY!
