They've analyzed the legs on Nat geo with the him Henson company, the top monster making and suit designers in the world, trying to recreate the biological structure for humans to match the leg proportions in a suit. It was impossible even after some 40 years later.
The leg structure of the sasquatche big foot was determined to be not human as the leg porprtions from foot to knee amd knee to hip are impossible for any human to match biologically.
Secondly the way the orginal monster turns with its entire upper body indicates there are no neck muscles that which humans have. It was determined this creature truly resembled an ape in its beck structure.
Lastly everyone on pol in this thread needs the final redpill:yettis, big foot, sasquach, skunk ape all are nephilim mixed with some kind of primate and other nephilim beasts making modern sitings. If not one here knows what a nephilim is they are an umbrella term for fallen angels mating with either human women or beasts including their giant offspring who genticly manipulated the rest of the earth.
These creatures are usually spotted in woodlands or near hallow earth entry points where they live.
(((Native))) Americans say the bigfoot have a spirit form as well. This plausible for nephilim, because most if not all nephilim that ever existed became demons, wondering spirits in different forms. This means that a nephilim big foot still in their wealthy bodies would be able to switch forms, but once they die in their earthly bodies they are cursed to wonder the earth and hell as spirit form demons.
