Actually Mulder, there is no evidence that can be conclusively attributed to a Bigfoot. There is plenty of evidence with claims attached that it came from a Bigfoot, but those remain just claims. Some of them have in fact been proven to have come from humans, i.e. hoaxed tracks. Samples have been proven to come from everything but a Bigfoot it seems. So technically speaking there is NO evidence of Bigfoot right now. There is evidence that is claimed to be from a Bigfoot, but to date none of that can be substantiated because right now there is no proof of Bigfoot to validate the claim. See how that works?
