Flat earth theory is that earth is a pancake (must sit on turtles all the way down) where north pole is at center and antartica on the edge.
They say that sun and moon just make circular patterns above the pancake, but that is still impossible as the sun and moon would still always be visible if it is just further away from your spot, and the sunrise/sunset dynamic can no longer happen. Even if you change it to a dome shaped pancake, to get some hiding of the sun, then southern hemisphere no longer has predictable daytimes.
