We know that the Antikythera mechanism was made in a shop, on a small production line, it was likely one of a series of devices made. It is possible that the orthodox timeline of the rise of man needs quite a correction, given the events at the end of the Younger Dryas. Many of the megafauna were wiped out, and mankind almost went with them. We need to survey the areas of the ocean less than about 200 foot deep (and the seabed below them) to see what mankind was doing before the sea level rose to the current levels.
