Because homo sapiens have killed off all other competing humanoid species in the last ~100,000 years.
Survival of the fittest ensures that if some species survived, they have to be specialized in avoiding humans.

Exactly.
What I find even more crazy is how other species of Homo were around until just 30,000 years ago and maybe as recently as 12,000. I find a lot of people have the perception that it was a much longer time but it could be as recent as the building of Gobekli Tepe.
Homo floresiensis sure, extend that a bit you can add erectus but after that? We don’t have a lot of closely related species in the last 200,000 years.
Non-human humanoids are instinctually perceived as threats even today in our uncanny valley response.
We would’ve found bones from Bigfoot by now.
I've been trying for decades now :(
