That's why cryptozoology isn't a science. There's no qualifications and no degrees involved. Call yourself an expert and go out into the woods and howl for a while and you're as much of a cryptozoologist as anyone else. IF smoking gun evidence for Biff shows up (a body or part of one), then the species will graduate into the realm of science and be dealt with and studied by biologists. 'Til then all the stuff mentioned is like I said before - just a bunch of stuff you can interpret depending on your own beliefs.
I agree with you totally. As in the case of big foot which everyone one seems to be interested and discussing.
I was in the mountains on a hike video in hand and a fellow hiker said look and we started filming what looked to me like what people call big foot. I thought, could be a stupid man in monkey suit although it looked real and was interesting to watch. I didn't think, oh I can post on Utube or something...didn't have that back then anyway...well I didn't become a believer because to me the evidence of video was not enough to even prove it to me.
Years later, a co worker went camping with family in another state. The son got photos of one running from their tent after it was stealing food from the tent during the night. They all saw him and are hard core believers of the big foot now and said it wasn't human and will never go back because it was so scary.
I think some things out there exist that are getting grouped together as big foot. They said the campground called it "grassman" because it built little huts from twigs and grass in the area. I've seen the huts before and thought, weird hunters, since I didn't hear the local legend until after that story. It was real whatever was building the huts and stealing food. I now know why the little campground is popular for more than the stables LOL. But it could just have been a mental case of a "wild man" since it was in the same region as a closed mental hospital in my opinion. After all, there are some really big hairy naked guys and they could go crazy. Photos were good but not enough to say he wasn't a big ugly hairy human with a Mick Jagger like mouth! They didn't go public.
I try to be open minded and say there's a possibility they exist but I don't have any evidence to rule out other explanations to myself.
