Hmmmmm, I don't see why sasquatch (bigfoot) is as comical or as unbelievable as ghosts, aliens or God. It's just an animal (if it exists) and it's not as if there has never been any upright apelike animals walking this earth.
Personally I find the idea some supernatural all powerful deity far more hilarious and preposterous, yet gazillions of people accept the Bible or the Koran and other such silly things.
I know a couple of people who are quite sure what they saw was a sasquatch. Both are hunters and both never even thought about sasquatch before. Both are now totally obsessed with finding out about this animal.
Actually there IS evidence for sasquatch. Just not verifiable proof. Unidentified hair samples have even been found. The famous Roger Patterson footage has still never been debunked and recent scientific analysis backs it up.
The Loch Ness Monster might well have a mundane explanation. Could well be a sturgeon or some giant eel. There have been sonar hits on large animate objects in the loch.
