After a digging stick, the ancient people learned to invent a hoe, which was intended for cultivating the land. We can say that she played the role of a plow until it was invented around 5 thousand years BC. At first, people used stone tools, since they did not know how to process metal, but over time, the situation began to change. So about 5 thousand years BC, people learned to smelt copper. As a result, the first metal tools began to be created, which were much stronger than stone ones.
