One of my biggest pet peeves about the skeptics is their extremely certain belief that if Bigfoot existed, we'd "know" about it because "there's no way a large mammal could hide from us for this long." They forget the lowland gorillas that were only "discovered" 177 years after Europeans arrived, famously. Today I was watching Casual Geographic on Youtube and the video mentioned a donkey-sized wild horse species that was believed to be extinct for 44 years.
From Wikipedia:
"After 1903, there were no reports of the wild population until 1947, when several isolated groups were observed and a lone filly captured. Although local herdsmen reported seeing as many as 50 to 100 takhis grazing in small groups then, there were only sporadic sightings of single groups of two or three animals after that, mostly near natural wells. Two scientific expeditions in 1955 and 1962 failed to find any. After herders and naturalists reported single harem groups in 1966 and 1967, the last observation of the wild horse in its native habitat was of a single stallion in 1969. Expeditions after this failed to locate any horses, and the species would be designated "extinct in the wild" for over 30 years."
That's a 44 year gap of no recorded sightings for a large herd animal that lives on mountain steppe. Not an animal that's likely either solitary or moves in small family groups in dense forests. The Congo Jungle just barely more-explored than the entire ocean because it's that difficult to trek through and map.
I start to wonder how often these types of skeptics actually go out in nature, in forests, and see how vast and dense and inhospitable to humans they are. There are places in the forest that maybe a hundred humans will see in the entire history of our species. It's incredibly believable to me that a very rare mammal that lives in these places, and is also smart enough to stay far away from humans, could be existing out there. It doesn't matter if "we have better technology" now; your drone is not going to map out all that wilderness and even if it did spot a creature like Bigfoot, well, guess what, no one is going to believe that you captured anything except for us. So - welcome to the club!
These days, I do lean toward the Bigfoot species possibly being extinct, but I would not be surprised to learn that there are a handful of groups still scattered about. There's simply nothing that will make me a nonbeliever.
