The creature, the primate we refer to as Bigfoot is an evolutionary split from us a long time ago. Where "we" developed our brains to work socially for survival they continued to develop theirs to work within their surroundings. They understand the environment far far far better than we ever will. Are they as smart as us? apples vs oranges people....apples vs oranges.
They show impressive problem solving that surpasses chimps and other primates. They understand door knobs and latches for instance.
