I don’t know.
There was a story from the 1960s or 1970’s from right here in Maryland, where a woman was driving on one of the highways - I think it was near Laurel, but I’m not sure - and saw something corresponding to ‘bigfoot’ come out of the woods near the road.
I don’t think I’m a very credulous person, but, again, it just seems to me that there might be something to this. There are just too many stories, going back over so much time.
On the other hand, the most credible person I’ve read on the subject of UFOs is Jacques Vallee; and he seemed to believe that there was some element of the ‘psychological’ going on in the stories of UFO; and perhaps that could be the explanation for Bigfoot stories, as well.
Eventually, we’ll know. In the meantime, it’s fun and very thought-provoking, no?
