This image is a parody of flat earth created by someone the flat earthers would call a globularist.

There are two “real” flat earth models. One is similar to this image, but the earth is encased in a dome on which the celestial objects ride. There is no outer space in this model, so there is no “other side” of the earth (or side walls for goats to tramp around).

The other model is an infinite plane. In this model, the North Pole is in the center and Antarctica forms an ice wall around the perimeter of the known earth. The government doesn’t want you to know about the lands beyond the ice wall, so they push the round earth lie.
