What did primitive people eat, what tools did they know how to make?

At first, primitive people were engaged only in hunting and gathering. They ate fruits that grew on trees and bushes. They also ate meat and herbs. Choppers and other primitive tools in the Neolithic were replaced by hoes, sickles and axes. Thanks to these inventions, primitive people were able to master agriculture and animal husbandry. These classes brought various products to people. For example, they received from animals: wool, milk, meat. And in the fields they grew grain crops.
