I watched an interesting video on The Ancient Study of Astronomy and this is my reflection. Three facts I learnt were that the Mayans, Ancient Greek and the Babylonians were acknowledged for their discoveries around the solar system. Babylon city state is located near modern Bahgdad. The ancient Greeks came up with the Precession of the Equinoxes. An understanding I had were that the people of the ancient times were very good at astronomy. Two things I’m wondering is how did the ancient greeks come up with the Precession of the Equinoxes? How can the ancient people work all these discoveries out?
