A pity about this good-natured fellow
In the first place, of course, he has a wife and children back in the den; and in the second, imagine yourself a fairly sturdy East Asian Homo erectus, in possession of a large brain, meeting a Flores or Luzon man, representatives of a race of little humanoids.
Undoubtedly, this meeting becomes the source of the so-called psychological phenomenon of the Uncanny Valley and of a deep, one might say instinctive, predisposition to notions of hobbit-like creatures and little demons.
If one thinks about the everyday life of primitive hominids, it is a daily thriller built on competing for food with two-metre carnivorous storks, on attempts to survive by eating giant rats and miniature elephants, and then one fine day monstrous dragons appear as well: giant monitor lizards, another undoubted source of archetypal and folkloric fears of dreadful creatures.
And quite another story is the epic moment of the meeting between the descendants of man, who had come down from the immaterial heavens, and the chthonic apes depicted above. The imprint of that moment in memory would lead to the appearance of notions of original sin, most probably a camouflaged interpretation of a prehistoric mixing of races.
