Simple. Because a species consisting of only a handful of members (at most) could not survive, and Bigfoot was first reported 200 years ago. That would necessarily be at least four generations, and more likely 6-8. Combine that with the fact that there's no proof of it and you've got a very unlikely creature.
Detail fail: No one mentioned that these things have to exist at this very moment.
About the evolutionary point of view:
Say, a branch of monkies that once existed, say, 300.000 years ago, developed a kind that mainly walks using 2 legs instead of 4 (like traditional monkies) but still were very hairy.
There you have it, a big foot. This species maybe lived for some time, then died out.
How is this not evolutionary possible? The way I see it, it has potential to exist - the way any of us exist.
