Born in doubt, make the money, ships, ships, people, gold, and the coconut in holes, enough time has passed, the villagers saw exclusive River basin present.
I suspect the villagers brought the ships, boats and golden coconut into the hole, leaving enough time to see the locals appeared at the river basin in the present.
Doubt makes people bring the ship money, ship gold and coconuts, dumped into the hole, over time the villagers saw up the water in the Mekong River Basin at present.
