I don't expect anyone to actually sit through this so I'll paraphrase. A suit maker for Jim Henson's studios says the technology to make a suit like the one in the famous Patterson-Gimlin footage (1967) did not exist until 1980.
It's also shown that the position of the joints (knees, hips, etc) on the creature seen in the footage is incompatible with humans so basically no human could be in a suit and get the knees/hips to bend in the places they bend in the footage.
The creature is estimated to be 7'6" tall.
So now that I've proven to "you people" that Bigfoot exists are your minds blown?
