The Patterson-Gimlin Film is a short video of a supposed Bigfoot taken on October 20, 1967 by Roger Patterson and Bob Gimlin. After over 40 years this film is the best evidence that Bigfoot exists. The film has been looked at many times by people trying to debunk or authenticate it and to this day cannot be explained. Many of the people who study the film are convinced that it could not be hoaxed, especially with the knowledge and technology of the time period.
