Well, I know a few people who believe there is a bigfoot, aliens etc... No proof of course, but when they watch the shows, and someone comes up with a good story about a bigfoot, or a UFO sighting etc... to them that's proof, or all the proof they need.
My wife believes a bigfoot exists; I do not. She seems convinced not from actually seeing one, but from the shows about Bigfoot that are on YouTube and such.
I myself saw something back in the 90's, I suppose if there were a bigfoot, it would probably pass as one. But I believe there ias a good explanation for what I saw, and it's not a bigfoot. It's on the BFRO website, if anyone is interested in reading it, let me know Ill get you there. I put it on the site a year or so ago, my wife asked me to, plus I was curious about what would happen (haha), then a month or so later, I received an email, and then a phone call. The person who interviewed me edited what I wrote, and instead, it was a bigfoot. But I still disagree. Now I know what I saw, but I do not see enough proof.
