Anyone experiencing an eclipse would know the earth is round.
WaeO: Yeah, the sun is round, the moon is round, and the light during totality on the horizon around the round shadow is round.
The bible still advocated a flat Earth in Jesus' "all the kingdoms of the Earth visible from a high enough mountain" temptation. Then, on a clear day, you could see forever, from Judea all the way to China' XYZ Dynasty.
The flat Earth has curled into a 3rd dimension since. but will have 4 corners again after the 1000 year reich. so, if it is the 3 dimensional, but with 4 corners, it must become be a 3 sided pyramid. ha ha.
