It is quite probable that early man ate naturally cooked food (as animals do today) from those burned in natural bush fires in dry areas.
It is also probable that in selected volcanic locations fires would start naturally or could be started simply by putting dry sticks into hot volcanic ground, as in the 4th photo on the link.
After you arrive at the visitors Car Park you will witness several demonstrations of 'how hot' the area is (temperatures just a few metres below the surface reach between 400°C and 600°C). Dry brush thrown into a hole in the ground catches fire immediately, while water poured into a bore hole erupts seconds later in the form of steam - like a mini-geyser.
