There's also legends about dragons all over the world, but do you see any of those flying around? Even if a bigfoot could hide out somewhere in the woods, there simply isn't enough resources to support a race of apes in the Pacific Northwest. It has nothing to do with intelligence, it's a matter of nature. This is also not to mention that the most famous sources of "evidence" towards bigfoot have been proven to be complete and utter hoaxes.
the length of this animals hair is unlike any other animals. it wouldnt be practicle for an animal to have such long hair. only dog breeds such as afghan hounds have such long hair and they where bred for that very characteristic. wheres the evolutionary step that says this thing, which i am asuming is supposed to be some kind of primate, shouldbe so unlike all other primates in that respect. Any suggestions? the scientific community would say Fake until proven otherwise.
it could b real, its not like your gonna call up like a zoo and say hey theres a bigfoot in my backyard they would never believe you so its not that hard to imagine weve never actually encountered one
