Yes, Bigfoot does exist according to one of my sources who I tend to believe. He has not actually seen the creature but he & his friends have experienced Bigfoot interaction such as tree knocking, etc. Also when they were using night vision.
Bigfoot was a hoax started in Northern California by a man named Ray Wallace. He and several others hoaxed prints and evidence. The media did the rest. I know this answer isn't much fun, but it's true.
I saw a documentary that proves me that they are real. The evidence was a movie and they stimulated that the movie is not fake. They used several ways and the answer was just one thing, the movie is real.
