So I'm channel-surfing, and I come across this reality show on one of the nature channels about some Bigfoot hunters traveling to various parts of the US trying to find evidence of Bigfoot. They all seem to believe Bigfoot actually exists, and do dumb things like point to a pile of leaves and claim they found a Bigfoot "nesting" spot. They also talk about various grainy photos they've seen or taken, plaster casts of footprints, etc - all easily-faked "evidence". These guys are either decent actors or complete idiots. They talk about encountering evidence of whole Bigfoot families, but of course they're shy creatures who know to avoid humans, and that's why there's so little evidence, and on and on. The obvious question which they never address (of course) is how come there's no bones or other remains which have been discovered to prove these creatures are real. What are the odds a large animal species, even in small numbers, exist on an inhabited continent like North America, and no one would ever come across a deceased one? I'd have thought all major human-sized or larger land-dwelling species would've been discovered by now (not counting minor variations on known species), but I'm no expert. Could a large land-dwelling and distinct animal exist on the planet which we've not yet encountered?
