Well, there is the pesky problem of knowing what tools bigfoot does or doesn't use. No facts are no facts. I personally ascribe to the notion that necessity is the mother of invention. So there is the question of what causes sasquatch to be brawny. Was it the inability to make tools as a selective pressure towards physical prowess or was the physical prowess always there, and thus precludes the need for tools beyond a stone or club? I think Sas has demonstrated that he's not making many mistakes, and if it was a mere animal it would have been proven long ago. People who can't see the humanity in bigfoot grossly underestimate this creature IMO.
