What changes have occurred in the social life of people in the Eneolithic era?

The Eneolithic period covers a time span from 8000-5000 years ago. In another way, it is also called copper, since at that time people began to make household items, weapons, etc. from copper. Thus, copper tools began to replace the old stone ones. During this period, agriculture and cattle breeding also developed rapidly. People have already thoroughly learned how to cultivate the land and get a harvest from it. The latest Eneolithic period marks the emergence of the first civilizations such as: Sumer, Egypt, China. Which, in turn, means the transition to the Bronze Age.
