In my present speculative considerations I imagine that a few different styles of humans evolved in the polynesian arkhipelago. Many islands lacked predators capable of killing humans, unlike most of he great landmasses. Looking at Easter Island I feel that islands 'ran out' of essential livingry forcing humans to move across the water to find new commodities. Apparantly in Polynesian society these navigator-priests live away from the main villages, and this tradition has continued to the present day. Though not living in a separate area Scientists often have info that others don't thus developing different mental landscapes.
Over millenia many sailed with the winds , out to Malaysia, China,Japan Siberia and back in along the west coast of the Americas. Others tacked against the wind reaching Africa using their shipping knowledge to create pyramids and such. To those landlubbers , Polynesians who left in earlier times, conveniently for my concept, lost or didn't need ocean-going skills as the continents provided ample sustenance. Rather like today once we get a stable lifestyle we often try hard to continue it despite the complacency and instinctual survival of the whateverist and become . I think, uncomfortable with our universal physical-metaphysical evoluting.
A story goes that the natives of Islands 'could not see' the ships carrying the Europeans as they had no concept with which to compare it thus , I think, non-ocean travellers would call the visitors Fish-men, as they called the Greek ships ' giant horses' because the y performed the duties once carried out by landed horse-powered soldiers.
Fish and Ships
These 2 concepts carry through into Pharoanic religion, Judaism and Christianity, my knowledge of other organized religions precludes me from further comparisons.
Ra regularly races around in its barque, Iheshuah Ben-Adam walked on water, got crucified on a mast, like Ulysses. Noah and the Ark heralded the new world order of men who built not towers but great ships. Building a tower on land does not require thinking about how much it weighs but a ship needs exact calculations and effishent use of materials to stay afloat. The great ships of business tend towards maritime language - companies are floated , launched, sunk. Limited liability law comes directly from the East India Company insuring of cargo and ship though not the crew. The owners would get paid off if their company sank.
Ships have new forms now - trains , planes and spaceships
