Bigfoot
Many eyewitness all across America have claimed to see a large, hairy manlike beast – yah know, Bigfoot. Thing is, despite thousands of sightings, not a single body has been found nor has one ever been killed by a hunter, a speeding car, or even passed away due to natural causes. Hard evidence like teeth, bones, hair and a body has never been captured, only eyewitness accounts and ambiguous photos and films support the theory.
