What are the undisputed facts about the bigfoot / Sasquatch mystery?

• It's a fact that for more than 400 years people have reported seeing large, hair-covered, man-like animals in the wilderness areas of North America.

• It is a fact that sightings of these animals continue today. Real or not, these reports are often made by people of unimpeachable character.

• It is a fact that, for over seventy years, people have been finding, photographing, and casting sets of very large human-shaped tracks. Most are discovered by chance in remote areas. These tracks continue to be found to this day.

• It is a fact that the cultural histories of many Native American and First Nation peoples include stories and beliefs about non-human "peoples" of the wild. Many of these descriptions bear a striking resemblance to the hairy man-like creatures reported today.

These are some of the facts. There is, however, much disagreement as to what these facts mean.
To many, these facts, taken together, suggest the presence of an animal, probably a primate, that exists today in very low population densities. If true, this species, having likely evolved alongside humans, became astonishingly adept at avoiding human contact through a process of natural selection.
To others, these same facts point to a cultural phenomenon kept alive today through a combination of the misidentification of known animals, wishful thinking, and the deliberate fabrication of evidence.
The BFRO, and its members, take the former view.
