From the youtube channel of Mr. Nightmare:
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. Couldn't find 10 good ones, so here are 6.
