In the WWII era there were cargo cults in the region that believed some pretty strange things.
:’) I remember an article about the cargo cult on one particular island; the article was probably in “Argosy” or “True”, and in the 1960s, when WWII was still relatively recent. The cultists revered the cargo deity they called “John Frum”, and even preserved a snapshot of him from the 1940s. The photo was of an actual US serviceman of course, and at that time he was still alive. I don’t think they were able to interview him, but that gave a brief rundown of his actual identity and the wartime work on the island. And imagine — that was a cult based on a distorted folkloric version of known historic events from just a generation earlier. :’)
Well when someone shows me how to quarry, move, float, host and place thousands of 10 - 50 ton basalt logs quarried, lifted and transported from islands, across the ocean, and into precise elevated placement at the site using stone age technology, I’ll stop thinking the natives are telling the truth when they say they didn’t do it. Because to me, a flying machine with a hot exhaust is exactly what one of these natives would call a dragon. And those stones are so heavy they’d make assembly even today staggeringly difficult, if not impossible. That’s just a fact. To me, that’s called a mystery, but I’m easy.
