It turns out the FBI investigated whether BIGFOOT was real back in the '70s after they found a mysterious animal hair they couldn't identify.
But here's bad news for you truth-is-out-there types: After a deeper investigation, the hair sample they tested from "Bigfoot" turned out to be from a deer . . . and the FBI concluded there's no evidence that Bigfoot is real.
The FBI just released the report on Bigfoot in the "vault" section of their website if you want to read it yourself.
