"One could imagine that a group of anthropologists and scientists sent off to study a previously uncontacted Amazon tribe today might be bound by similar strictures [not to reproduce with natives]. But suppose some of them disagreed? Suppose some of them "went native"--as used to be said of colonialists in the days of the British Empire who allowed themselves to get too close to indigenous populations they interacted with. Is that perhaps what happened to the troop of two hundred "Watchers" on Mount Hermon? Somewhere around 10,900 BC, did they break the commandments of their own culture and "go native" among the hunter-gatherers of the Near East? And were the first chance encounters with the fragments of a giant comet a century later in 10,800 BC--encounters that devastated the world--somehow blamed upon their moral lapse?"
