The Most Believable BIGFOOT Sightings Footage

The existence of Bigfoot has long been debated, and though there is no "official" evidence of its existence, there are some that devote their lives to finding one. There are even shows devoted to finding one, like "Finding Bigfoot." Here are perhaps 6 of the more believable ones (if there are any) that you can find on the web.
Thank you Jaden Ballentine for the suggestion.
While researching this, I can't tell you how many times I read something like "big foot experts confirmed this" or "Sasquatch investigators were able to determine." Who are these people? How do you become an expert on something that has a debatable existence?
