This is such an absurd take. There's people in Europe who believe that Europe's megalithic structures were built during the time of Atlantis and devote their whole existence to proving it, just to give one example. And of course, Stonehenge, neolithic Europes intergalactic landing site/astronomical calendar/astral energy power plant.

Megalithic structures like the Baalbek stones or Göbekli Tepe from preliterate times are aweinspiring enough to get anyone's imagination going, it's that simple. And some people then have a hard time distinguishing their imaginings from reality. They seem impossibly large and their purpose and methods of construction are lost to time, so it's easy to come up with fanciful ideas to fill in the blanks. Sure, we now have decent theories of how the pyramids were built, but that weren't always the case.

Castles and cathedrals were built too recently for even the wildest of wild brains to believe they weren't built by humans.
