I think flat earth is just the beginning of it. Not only is the earth flat, its highly likely we are living in a simulation which would explain why we cant go to outer space or go beyond antarctica. Like a video game you cant leave the bounds of the game. If our world or simulation was created by a creator, it would be so much much easier to do on a flat earth construct. The data required to simulate the mainstream cosmology would be infinitesimal.
