A bizarre video appears to show a UFO arriving at earth through a bright blue wormhole - or at least that's what it looks like.

The footage, shot at an unknown location, looks like it shows a space ship being beamed down to earth via a bright blue tractor beam.

It is not known who shot the weird clip - or what it really shows - but it was first posted on a Spanish Facebook group.

The clip has sparked a debate online as people argue over whether the video is real or fake, and what it actually has captured.

Many have argued that the video is a spoof and that it was made to attract money through the advertisements that feature before a video on YouTube.

Others think it could be a natural phenomenon such as lightning.

While it is not known where the shot was captured, Nevada and Arizona are hot-spots for alleged UFO sightings - leading some conspiracy theorists to suggest a spaceship could have been spotted there.

Scott C Waring from UFO Sightings Daily told the Sun: 'Arizona is a famous hot-spot for UFOs and Alien bases, so its nice to get this substantial evidence of their existence in that area.

'This is an alien ship, shooting off through the clouds, leaving earth.'
