Ancient people knew the earth intuitively. What did ancient India propose and what did China propose? What does the sky think of the earth?

The ancients thought that the earth was flat by feeling, and when they saw the sun and the moon rising and setting in the west, they thought that the sky was round. They believe that "the sky is like a round cover, and the earth is like a chessboard", and the round square hole money is the embodiment of the "theory of a round land". Later, the ancients felt that the ground was not so flat by feeling, and put forward that "the sky is like a hat and the ground is like a cover." The theory of circular venue was put forward by westerners.

The history of human exploration of the universe

The world view that western scholars can get at first is geocentric theory. This is a very rigorous mathematical model, which was completed by Ptolemy. In this theoretical system, human (the earth) is the absolute center of the universe, which is also very consistent with the religious world view. Therefore, this theory has been circulated for 1000 years.

Later in the Renaissance, there was a man named Copernicus who thought Ptolemy's Heliocentrism was too complicated. So, Heliocentrism put it forward, but it didn't cause any waves at first, because people at that time were hard to understand.
