Like the other skeptics in this thread, I can't believe that he (it, they?) exist(s) due to the likelihood of being found at this point without being in an ocean trench or some remote part of the world where humans just don't go.
However, it's kinda fun to entertain the idea. Who doesn't like driving or walking around through the woods looking for something cool/weird/scary? Combine that with the excitement of being the first to find or prove the existence of something novel and I get why it draws people in, and if I had the kind of spare time required to entertain such a hobby I could imagine getting into it just for fun. Like when I joined a hobby group centered around preparing for a literal zombie apocalypse. I got to go shoot guns and met a lot of interesting people.
