Please read the post before commenting and please don’t go into hyperbole and conjecture. I am going to try to make this as concisely scientific as I
can. I titled this the way I did because I will not rule out that possibly long ago such a creature did exist. I don’t believe it but I will concede
it is possible however unlikely, because many ancient tales by societies like the Native Americans and China and such have been proven to be based in
fact and wrapped in myth. I would say that just because there are these oral traditions, from peoples that often had other animals as their gods, it
doesn’t make them true. I will say that no complete skeleton has ever been produced of this creature and we do have the bones of Dragons (Dinosaurs).
So that is where I stand on this, I do not believe they ever existed but will only argue that they do not exist today. In fact I think I can prove
that no large Mammal exists that we have not found. The reason I use mammal is because of the descriptions of supposed sightings, this would likely be
a mammal with it’s size and other features.
To do this some scientific principals and known statistics must be accepted. The first one is archeology and bones and fossils, not huge for this
topic other than there is no Archeological Evidence for Bigfoot or Yeti yet unearthed. Next we would have to agree that if this creature existed it
would be either Humanoid or Great Ape most likely but surely a mammal and therefore have the lifespan and predators of these classes and sizes of
animals. That would mean probably if Bigfoot existed they would live a natural lifespan of between 60 and 80 years. I wont argue that it couldn’t be
40 or 100, but its a fair number I think. And with those ground issues in place I will attempt to prove it can not be.
#1. Bigfoot if it existed would have to have been around for a while, it would not be some new evolutionary species, precisely because we have the old
tales from some cultures of these Yeti/Bigfeet existing. If it was plentiful in the past and is going extinct now we should still have some evidence
of some kind, bones or dead bodies or pictures. It’s not like they live underwater where man is not at a lot, they are claimed to be larger than men
#2. Science has proven in population studies that if a society does not maintain a growth ratio of 2.7% it will disappear. This means that you will
eventually level off with deaths (natural and untimely) and births, but this doesn’t level off until you have a large population. So small groups of
these creatures or lone ones could not maintain a population for very long before it just did itself in. Of course this number changes for conditions
like desert and food supply and deaths, but I am using the American model for this. In Africa they have to have a larger # of children to maintain
that growth ratios of 2.7% because so many die young and do not live to reproduce. I would even be willing to lower the needed growth rate for a
creature with no natural predators and one that ate a healthy diet and lived a long time naturally and often. Of course that growth rate has to be
maintained or extinction will come but I won’t argue that it wouldn’t be a slower process for extinction with such an animal, but eventually even it
would die out. Possibly this is what we are seeing now with so few real sightings of something if it were Bigfeet. Maybe we are watching their
extinction, but I don’t believe so because of the other missing evidence that a large population ever existed.
#3. Hunters – There are not many natural vast expanses of wilderness, particularly in America, left for these creatures to live undetected by someone
at some time. And since many of the sightings are coming from inside towns and residential centers one would have to think we are encroaching on such
an animal if it existed. How is it that no hunter has ever got one? How is it that, like with deer and moose none has been hit by a car. How could
they not be spotted all the time like bears and elk and moose and well everything we have in this Nation is and has been seen numerous times and shot
and photographed and documented. Even the nocturnal creatures and surely all the large ones. It could not be assumed it would understand roads and
cars and know to look both ways before crossing. There is a disturbing lack of any evidence here in the Hunts and accidental car hits. All those
hunters in all those woods in all those tree stands and not one ever shot? All those roads in all those towns and not 1 hit?
#4. Sightings (so called) – With all the technology especially today how is it that no one can get a picture of these things that is definitive? Trail
cams and hunting cams and all the surveillance done now in America like looking for drugs by air and drones and Satellites. Again we could not assume
they would know a trail cam and avoid them when walking in the woods at night or day, it would not understand photography which is why trail cams work
for hunters. A community of any size would have to leave traces in the woods and these could be spotted and found by accident, yet not one Bigfoot
community or home has ever been found. Starting to look more Great Ape than Humanoid based on this fact, if something exists.
#5. Wilderness – Already mentioned there is not a lot of places or large areas that man is not in at some time or another or watching. And as we have
taken up land and encroached deeper into the untame areas not one picture, body, bones, homes, nests again it is just not been found in any form live
#6. Bones – Archeology has not ever found a complete skeleton and I don’t think any individual bones. But even if one or two unknown bones were
around where is the rest of the bones and there should be many bones of these creatures found by now. No bones after forest fires have been found, no
babies bones even.
#7. Predators – If this creature was living in North American Wilderness areas it would have no natural predators for its size except possibly an
occasional Grizzly and man. Again no bones have been found from a bear feast or a hunter the only two predators that could maybe take down something
#8. Food Supply – If it was strictly a herbivore it could have an unlimited supply of food depending on the diet. An Omnivore would also be presumed
to have a good food supply just supplemented with meat. A strict carnivore is a lot less likely just because of the amount of food that would be
available to such a large creature in many places where they are claimed to be sighted. And we can assume from man and ape and our diet that they
would likely be omnivore’s or herbivores. So a nearly unlimited supply of food should make most animal species grow large and sustained but again we
have no evidence of such large #’s of any creatures this size anywhere yet.
#9. Life Span – We covered this a bit already. If they are herbivore’s only and humanoid or Great Ape we could expect a lifespan of upwards of 80
probably. The herbivore would have a natural food supply and a nearly unlimited supply of it which would lead to longer lives too.
I think one can safely say that there are no large unknown Mammals left. I believe I have laid out a case that shows how unlikely it could be that
such creatures exist with so little evidence in so many fields.
