Actually, "Bigfoot" only refers to the large bipedal apes alleged to live in North America. Perhaps whatever made it popular has been debunked, but alleged sightings of the sasquatch go back further than that.
Also, stories of ape-like hairy wild-men exist all around the world, and have existed for centuries. In Germany, there was the "schrat". (interesting fact: Schrats were featured in the 1993 computer game Darklands, which takes place in 15th century Germany. In one possible scenario, they try to steal a female from your party.) There is also something in Russia, though I don't remember the name.
If any of these are discovered to be real, they probably won't be called bigfoot.
The Ebu Gogo legend from Flores is evidence that Homo floresiensis may have survived up until only hundreds of years ago and may still possibly be alive. Also from that general area of the world is Orang Pendek, which supposedly looks like a small bipedal orangutan. These cryptids walk like humans, but are small.
DogSRoOL, people may have quoted only portions of your post, but the responses certainly work for your post as a whole...
I just looked up some info on the schrats:
Along with the similarity to bigfoot/yeti type creatures, it seems interestingly similar to Ents.
I'm just a little boy.
