The origin of the constellation:

Mesopotamian astrologers divided the starry sky into several regions for the convenience of studying and observing many stars in the sky, and each region was a constellation. It's hard to say clearly when humans began to have the concept of constellation. This astronomical knowledge was known long before there was a historical record. The name of the constellation probably comes from the sailors who sailed early. ?

The origin of constellations may be completely different between civilizations in different regions, but with the expansion and mutual influence of civilizations, the culture of constellations also includes the process of integration.
