World's oldest campfire? Ancient flint tools show humans may have tamed fire 1 MILLION years ago

Scientists think they could have come across the location of the world's oldest campfire - and it's over a million years old. Flint tools and animal bones had been excavated from a quarry in Israel, thought to have been inhabited by our ancient ancestors, Homo erectus. Researchers investigated the ability of these artefacts to absorb ultraviolet (UV) and infrared (IR) radiation – which is affected by burning. They compared the results to those from similar unburnt materials, and concluded that they had been heated to temperatures between 390 F (200 C) and 1100 F (600 C). The team from the Weizmann Institute of Science in Israel also analysed bits of tusk from of an elephant-like animal that had been found in the same sedimentary layer as the tools.
