Why did the ancient Egyptians divide the sky into 36 constellations?

In order to facilitate the observation of astrology, first, ancient people were superstitious about divination, and second, scientists who studied astrology. The former is the origin, and the latter is based on the former. But ancient humans also knew a lot of science, and divination also needed evidence, such as a well-known example: Maya. Their predictions succeed every time.

1: The end of Mayan civilization. That is, his own end, he predicted it himself. But that won't change. (Implemented)

2. The appearance of cars, planes and rockets. (Implemented)

3. The approximate period of the birth and death of the Great Devil (Hitler). (Implemented)

4. The outbreak of a devastating war (World War I and World War II) (realization).

Maya knew all this through astrology.
