How did farming and cattle breeding change the lives of primitive people?

Agriculture and animal husbandry enriched the life of primitive people. Before that, they were engaged in ineffective gathering and hunting. They spent most of their time chasing prey or finding an edible fruit. After they began to grow plants and raise cattle on their own, they began to arrange sedentary places of residence. Ancient people began to produce more resources. Because of this, they began to have surpluses, which they exchanged for other products. This is how the first noble people appeared.
