We are sailing, we are sailing
I've never understood the archaeologists' determined refusal to admit that ancient man sailed on the oceans.
The desperation to 'prove' that they didn't is bizarre. If the water close to the cliffs is really deep that just means it is the OCEAN, on which you need a vessel that can cope with being on the OCEAN in order to fish there, regardless of whether it's 1 mile of 20 miles off-shore. Sure they can't find evidence of the boats, but by the same token they can't find any evidence to disprove the presence of boats but have to explain the inconvenient presence of lots of people on islands. Apparently they drifted there by accident on logs; I mean, come on.
