Put another way, neolithic people weren’t able to survive such a long voyage until they figured out how to bring along sufficient supplies of food, and keep it dry and on board their boat until they made landfall.
Pretty impressive, nonetheless. The equivalent of a voyage to Mars today. Maybe even a bigger lift — they didn’t know that anything was out there at all, let alone where land might be found. One imagines that they were driven by great need or desperation, along with substantial courage and ingenuity.
Uh, no. All they had to do is gather up material that floats for making a boat, store food in watertight containers, and then sail away. That is a far cry from a mission to Mars.
Assuming neolithic people had roughly the same intelligence that we do, why would anyone find it exceptional or noteworthy that, when departing on a voyage of uncertain duration, they would take food along?
