From what I have looked at, I believe the "Sasquatch people" are another species of human - larger, much stronger, highly intelligent, and well-adapted to living in wooded areas undetected.
I believe the US Government knows exactly what they are and has taken many steps to keep them segregated from contact with humans. Some claim their elusive abilities are paranormal (multi-dimensional travel), or technologies gifted to them by alien races who use them to watch us. Obviously, there is minimal proof of these latter claims, but a lot of stories suggesting unusual gifts do exist. One ability they apparently possess that is not paranormal is infrasound - the ability to emit a low, subsonic noise that terrifies their prey animals like elk and deer (and unfortunate humans) in the vicinity. Tigers also use infrasound for the same purpose.
Every native American tribe knows about them and has names for them. Some native Americans insist they can speak native tongues and that before whites came to the continent there was much more intercourse between them and the tribes. White guns drove them into the deeper woods (it's always Whitey's fault) and they became very distrustful of humans. That may be where Missing 411 comes into play. Some of these creatures have a somewhat benevolent attitude toward humans - especially children. Some do not.
With a small population, inbreeding would lead to many genetic defects. This could be why some have been described as looking like they have Down's Syndrome, and others are very aggressive and violent.
Bones or bodies are never found because - like humans - they bury their dead. Evidence suggest they dwell in caves and are nocturnal - they hunt at night and have tremendously sharp night vision. They may have the ability to see infrared light, They seem to travel in small family groups. If a hunter shoots one, he may have four more on top of him immediately - and would not likely live to tell the tale.
Sasquatch people have been sighted in all of the Lower 48 states and Alaska, as well as in many other countries around the world. For the most part, they seem to prefer to leave humans alone - and in turn want to be left alone. There are exceptions, so trips alone into the woods are more dangerous than the authorities (the same ones that tell you Biden won the election...so shut up) will admit to. Some of the Missing 411 stories are no doubt the result of an encounter with a Sasquatch - David Paulides hints at this but always leaves the viewer to draw his/her own conclusions.
For a no-BS approach to the subject, I recommend Steve Isdahl and howhohunt.com on YouTube. He is a friend of David Paulides of Missing 411 - a professional hunter who gathers Sasquatch stories and reads them while in scenic locations in British Columbia, near places where sightings have been reported.
There are thousands of detailed accounts out there. Many are no doubt carefully crafted works of fiction - others are silly, like the countless low quality fake videos on YouTube. But if even one account is true, then Sasquatch exists.
That's all I know - none of it from first-hand experience. Other posters on FR have mentioned first-hand encounters, but are naturally reluctant to say much about them.
Very interesting, thank you.
