Random Tin Foil Hat Thought,

Humans naturally are afraid of things that look human but are not, (Uncanny Valley Effect) why would we evolve that way? Would it not make sense its because at one point we had a predator like that.

By that same logic, wouldn't that predator adapt to look even more human so to be able to capture its prey easier? By thier own evolution they are able to move themselves into human society and live amongst us eventually ruling over us? (If not create the society)

More proof could be, what do predators normally target? The young of another species, what if pedophiles are either hybrids or the other species altogether?
