Where did the constellation originate?

Constellation originated in Babylon, one of the four ancient civilizations. The Babylonians divided the sky into many regions and called them "constellations", but at that time constellations were of little use and were rarely found and named. The constellation 12 on the ecliptic was originally used to measure time, not to express people's character as it is now. Around 1000 BC, 30 constellations have been proposed. The Tigris River and the Euphrates River flow into the Persian Gulf from northwest to southeast, so it is also called the "two river basin" area.
