How did ancient people discover fire? This question involves the human understanding of fire. The earliest fire was discovered in the era of human hunting and gathering. In the early days of human life, fire was a very important tool that could be used for lighting, cooking, roasting meat, fire prevention, and many other purposes. In ancient times, there were many ways for people to discover fire. One of the common methods is to create sparks by rubbing stones or metal objects. When the sparks fly, they will produce flames. This method of discovering fire is called "friction fire" and it first appeared in the early era of human hunting and gathering. Another way to find fire was to use a torch. Torches could burn wood or other flammable materials to allow people to observe and illuminate from afar. In ancient times, people usually set up torches in camps or caves to hunt and gather at night. There was also a special way to find fire called " lighting a fire." In ancient times, people would usually place firewood next to a fire. When the firewood was lit, the fire would burn. This method first appeared in the primitive society. People used bonfires to keep warm and light up. In short, ancient people discovered fire through many methods, including friction fire, torches, and igniting bonfires. These methods of discovering fire not only helped humans gain more convenience in their lives, but also promoted human understanding and exploration of nature.
