If you watch any of these “historical documentaries” about visitors from outer space interfering with our ancient progenitors, you’d see the proponents of these theories claim that there is no way that massive sculptures and architecture could have been done without extraterrestrial help. Those mainstream historians and archaeologists just don’t understand when they claim that the evidence of UFOs and aliens in old artwork or texts is something more reasonable, when they posit some Earthly, mundane explanations.
Our ancestors, the ancient alien experts claim, weren’t stupid. And the official story makes them seem dumb, by not giving them the full credit they deserve for recognizing obvious aliens when they saw them, and then sitting back as said aliens (or gods, or whatever) did all the work that our stupid, useless ancestors could never have figured out on their own.
But they weren’t stupid. They were able to make complex astronomical calculations, invent forms of art, agriculture, writing, and design marvels such as the pyramids. Some of them would have been smarter than others, of course. Some of the people of that age probably believed some really weird things; perhaps they believed that their ancestors were visited by even more ancient aliens, whom they gave all the credit for all previous human efforts, without any evidence.
I’m just saying that their knowledge and sophistication was limited by the understanding of their time. People would have made dumb logical fallacies back then, like arguments from antiquity or arguments from ignorance.
Hm. Come to think of it. If we had aliens helping us out throughout history, we’d probably be a lot further along, and wouldn’t fall in such intellectual gaps.
