Okay, if it was shown to you that all the “evidence” supporting the idea that he exists was faked, would you accept that there was no reason to believe? How about the people involved in faking the evidence explaining to you how it was done. How about being shown the origins of the idea, that were clearly written as fiction? What if the entire us army devoted five years to searching every inch of Washington and Alaska, going so far as to burn down every tree and raze every building, and came up with nothing?

There is some reason or reasons you decided to believe in Bigfoot. If those reasons were shown to be invalid, would you accept that it is more reasonable to assume that there is not a giant hairy half-ape/half-man creature who has managed to avoid capture and whose existence can’t be anything close to “explained” by everything we know about the world?

If you know why you believe in something, or don’t believe in something, it’s not that hard to see what would change your mind. If you don’t know why, shouldn’t you figure it out?
