Flat Earth
The earth is a flat disk. You may think that is a sphere, but much evidence exists to the contrary. For example, the horizon is always flat, even when seen from great height, like an airplane. The photos from space are inconsistent at best, conspiracies by NASA at worst. And there is no way to disprove a flat earth. You can circumnavigate our planet in its planar form by sailing or flying around its disk. Erathostenes assumed that the earth was a globe when he calculated its circumference thus creating false logic. The sun orbits around the axis of symmetry above the earth creating days and seasons. There is no proof, my friends, of a globe-shaped earth. You simply believe that because you have been told to believe that and never doubted it.
