I’m convinced that these conspiracies are spawned from racism towards non white civilizations. It’s easier for them to believe an imagined space God came there and built something rather than the indigenous people. There is also probably some need to believe that we are always at the peak of human progress in all things but in reality the story is more complicated.
I’ve used a start menu alternative since I switched to 11. I get the hate for the os but it’s all just been a non issue for me.
