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 by most.

#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 or dead.

#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 so big.

#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.

Well on destination truth, some monks stated they still have a head of one of the creatures inside their temple, although they would not let anyone take dna samples, but did let the crew see it.

You are assuming this is a normal creature, but what if it doesn't fit the mold.

Well many hunters have stated that when coming across one they didn't feel like it was an animal, and more so like a intelligent person, and felt that it would almost be like murder, which is understandable. Also would you shoot at a human looking creature standing 9 feet tall, who can sprint faster than an olympic runner, and pull a tree out by it's roots? I certainly wouldn't.

Well no picture is considered definitive, not even high resolution. There have been many videos and pictures taken, but again, no picture or video is ever accepted as proof. You are also assuming these creatures aren't that smart, but how do you know? Perhaps they exceed our intelligence. They have also been known to cover their tracks in snow, that doesn't sound like a dumb animal.

There have been shelters found. As for the bones, perhaps they bury them, like we do.

That is a mystery, but again we assuming based off our own experiences, but what if bigfoot is something completely different?

Going by how people describe the bigfoot, I wouldn't think it would have any predators.

That's assuming that it acts like a normal animal. Perhaps they are conservative, another sign of superior intelligence.

They have been seen spearing fish, so I think they take in a wide variety of food sources.

Closed-mindedness and narrow thinking are why science doesn't move ahead as fast as it could. "You don't think so" is not a scientifically valid statement. You attempting to back it up with absent evidence is about the worst scientific thinking possible.

Not very thought-provoking thread. Provoke thought: Don't kill it.

Science (big S) doesn't want to support UFOs, ESP or most conspiracy theories either.

So what does this prove? Do they then not exist?

Does Science prove evolution, when the pyramids were built, when the Americans were first visited by humans?
The list goes on....

You will make a very good conventional scientist, however.

Do you not think there is a chance they are a subterranean species that operate in ways we don't understand?

Even a simple idea like that seems to debunk most of your points...

Not scientifically possible?? Well since scince is always right, and never make mistakes.... there are loads of information and proof of the existance of these creatures. Try countless stories from different cultures around the world. Thousands, maybe even millions of stories in modern times. Countless expidetions, yes many have been unfruitful, but just as many have produced evidence. There's tales from pretty much every continent, talking of a large apelike creature that roams places uninhabited by man. There's also stories passed down of a large manlike beast, that had the ability to change into any animal at will. Just a few points I wanted to throw out here, I hope it helps.

saying it CANNOT exist is just plain ignorant, this is simply a troll thread
