Why have people since ancient times been interested in the planets, the Sun, the Moon, the stars?

People have long been interested in the sun, moon and stars. This is quite normal, because science in ancient civilizations was very developed, and religion, as in the Middle Ages, did not interfere, but rather helped them. Of course, seeing the stars in the sky, they thought about their origin and watched them. For example, they learned that the ebb and flow of the tide depends on the moon, so that other processes could observe and make their assumptions. And they were also sure that the stars tell the fate of a person.
