Recently I was thinking a bit more about the notion, beloved by liberals and atheists alike, that Bible writers believed in a triple-decker universe. On this view, as I understand it, there was a central landmass which floated on the primordial sea. The sea was under and around the land.
Let’s bracket inspiration for a moment and just consider if this would make sense to an ancient Near Easterner, with no modern scientific knowledge. What would that cosmography entail?
Well, on that view, the earth would be a boat or raft at sea. And that’s something ancient fishermen and mariners were acquainted with. But in that event, you'd expect the land to bob up and down with every wave and ripple–like a waterbed or cork in a bathtub. But although ancient Near Easterners experienced the occasional earthquake, life on dry land was quite different than stepping into a boat.
It would also be a pretty top-heavy ship, what with those mountainous pillars supporting the solid dome overhead. During an earthquake, wouldn't the ship capsize?
