IIRC Sapiens, Neanderthals and Denisovans coexisted for some time, so it could be not about things that aren’t human, but humans that are different. To this day, xenophobia and ethnocentrism are common attitudes.
Yea but homo sapiens and homo neanderthalensis definitely interbred. A lot. A measurable chunk of modern human DNA is neanderthal in origin. The uncanny valley being there to spot sick and dead people is more likely.
