Although more recently the technology has fallen into obscurity, flintknapping has for millions of years stood the test of time, far longer than anything yet mentioned here, and whether we're aware of it or not, we all owe considerably to whomever came up with it, along with the inventor of the wheel, as well as whomever developed the ancient and mysterious techniques to control, use and even create fire, not to mention, of course, whatever unknowable creative geniuses that invented throwing, food, sex, clothes, pockets, wiping the nose, wiping other things, etc. Come to think of it, there was likely a first individual that came up with adding and others for each operator, and these inventions must have occurred a very long time ago yet many still use calculation even today.
