>>5029763You can disprove the flat earth model with some pretty basic observations.
Anybody in the Northern hemisphere can look up and observe the constellations rotating clockwise around a single, fixed point over the northern horizon. This point lies directly over the Northern pole and marks the axis of the Earth's spin.
Subsequently, anybody in the Southern hemisphere can look up and observe the southern constellations spinning counterclockwise around a single fixed point over the southern horizon. This could not happen unless there was a South Pole. There is no way to make this observation fit with a flat earth model.
Anybody can observe this phenomenon for themselves. The easiest way is to point a camera at the night sky and take a long-exposure photograph.
