"Fire making, fire lighting or fire craft is the process of starting a fire artificially. Fire was an essential tool in early human cultural development. It requires completing the fire triangle, usually by initiating the combustion of a suitably flammable material.The control of fire by early humans is said to date back to either Homo erectus or very early Homo sapiens: that is, 400-200 thousand years ago, based on archaeological evidence of hearths."@en . . . .
