I'm going to rent QUEST FOR FIRE and practise with all my methods while watching it. One of the artifacts found with Oetzi was the remains of a live coal carried on his person along with sparking kit. I would argue the many 'Sacred fires' of many peoples are just that, recognition that fire is what makes us unique in all of Nature and creation. Primal peoples ( I hate the perjorative primitive) simply didn't wait for a blizzard to start making fire from scratch 24/7. Man standing nekkid in the wilderness with only his knife is mere romantic hubris, aka stupidity.
