INDEED. In fact, it is ludicrous to think otherwise. When has there ever been a seaside people who did not know how to exploit the sea?
Boats might well have preceded the invention of the wheel, but by 30,000 years or more?
And it’s one thing to invent a boat to get across a gentle river or small lake. Using the technology available 40,000 years ago, can you explain an ocean transit?
It couldn’t have been anything better than a dugout canoe. I don’t know how you could have even stored enough drinking water for one person for such a trip.
