The meaning of fire for primitive people.

Mastering the technology of fire made a revolution in the primitive life of ancient people. With the help of fire, people have been able to significantly expand their diets. The fire scared away wild predatory animals and parasitic insects. This means that far fewer people have fallen prey to predators and fewer have died from insect-borne diseases. People were able to be active at night because fire gives light. The fire heated the dwellings. Over time, people have noticed that some stones become liquid in the fire. And this is the beginning of metal processing and a huge leap forward in the development of civilization.
