What is the most important discovery of humans?
Fire
Fire is universally accepted as important to human life, with myriad expressions and uses in the modern world [1–7]. It was regarded by Darwin as the greatest discovery made by humanity, excepting only language [8].

Why was the discovery of fire so important?
The discovery of fire, or, more precisely, the controlled use of fire, was one of mankind’s first great innovations. Fire allows us to produce light and heat, to cook plants and animals, to clear forests for planting, to heat-treat stone for making stone tools, to keep predator animals away, and to burn clay for ceramic objects.
When did people first start to use fire?
An Ongoing Discussion. Archaeologists examined the available data for European sites and concluded that habitual use of fire wasn’t part of the suite of human behaviors until about 300,000 to 400,000 years ago. They believe that the earlier sites are representative of the opportunistic use of natural fires.
Why was fire so important in the Stone Age?
Obviously, they cooked their food, but the use of fire went far beyond that. For one, fire was an important part of other technological development in the Stone Age. Stone tools existed before the advent of controlled fire, but Stone Age humans combined the two technologies.
When did we start to find evidence of campfires?
Starting about 400,000 years ago, we begin finding much better evidence for human-controlled fire, such as intact campfires, or “hearths,” that contain concentrations of charcoal and ash inside caves, where natural fires don’t burn. Furthermore, the number of sites with such evidence increases dramatically.
