Life influence

The use of fire first enables humans to form and popularize cooked food life. In particular, the invention of artificial fire enables human beings to eat cooked food at any time, reduces diseases and promotes the development of the brain and the evolution of the system. The popularity of cooked food has also expanded the sources and types of food, and finally liberated mankind from the era of "drinking blood raw". Fire also brings warmth to human beings, thus expanding the scope of human activities, so that people are no longer limited by climate and region and can live in cold areas.

Fire and social production

Fire is one of the important means of primitive hunting. It is effective to drive and round up wild animals with fire, which improves the hunting production capacity. Burning grass as fertilizer promoted the growth of weeds, which was naturally inherited by later nomadic tribes. The primitive agricultural farming method-slash and burn, is carried out by fire. As for the primitive handicraft industry, it is inseparable from the role of fire. Bows, arrows and wooden spears must be baked with fire. Pottery and smelting in the future can't be done without fire.
