Even for copper, a campfire is a couple of hundred degrees short of the needed temperature which means some unknown genius had to figure a way to make fire hotter. Now, we have to move the date back another 600 years.


I believe there is evidence the Neanderthal had the skills to heat tree barks in oxygen free environment up to well beyond normal temperature achievable in a camp fire to turn them into a resin like glue for holding stone spear points to wooden shafts.

This glue can't be made naturally because tree bark will burn long before they reach the temperature for this glue to form.
