The Mothman is a mythical creature (although some would dispute the mythical description) which showed up in West Virginia in the late-1960s, supposedly.
This video is a short documentary looking at the creature and some of the sightings of it. You may not believe the creature is real after watching this clip but you will at least have a better idea of what the Mothman is.
The first recorded sighting on Mothman happened in 1966, although it was known as Big Bird at the time. There were further sightings over the next few months, ending in 1967.
What is the Mothman? Some think it was a hoax, some think it was part of a conspiracy. Others believe it was a misidentified bird, while others still put it down to parapsychology.
In essence, no one has a clue. So it’s just like Bigfoot and the Loch Ness Monster in the regard.
