>>19250453>ideaHave you ever looked outside? Flat earth is literally everywhere. You have only ever seen flat earth since you were born here in this existence. This is the only physical reality you can observe, measure, and verify. It's not an idea, it's the outside world.
The idea starts when people showed you cartoons in books and on television, showing you curved oceans and an atheist big bang space void with gaseous balls flying around each other. Exploded from nothing since the Jesuit George Lemaitre came up with that idea in 1930. All that stuff is human ideas that you will find nowhere in physical reality.
