"Back in the caveman and cavewoman days, someone had the idea to try to create fire artificially. They had seen the heat generated by forest fires started by lightning, and they thought that fire would be just dandy to create heat and light at night and to cook meat. They were tired of eating raw meat. Since people had noticed heat was generated by rubbing sticks together, some had the idea to rub them together faster and faster. Eventually here and there people claimed they were able to start fires by this method..."
