This recently rediscovered vintage video of possible UFOs caught circling a remote field might prove the theory has been right all along.

In the 1989 clip, filmed near Oliver’s Castle in Wiltshire, small white dots appear to be flying haphazardly above a deserted cornfield.

As the small objects travel at speed around the field, circular formations begin to appear in the corn beneath.

Suddenly, the UFO-like objects disappear, leaving only the the mystery circles in their wake.

Crop circles first came to the fore in the 1980s, when they became a subject of mass speculation by paranormal investigators.

Many believe they are a sign that extra terrestrial creatures are trying to communicate with Earth.

Several scientists have tried to discredit this theory, arguing that there is no proof crop circles are caused by aliens.

However, a research professor at the National Institute of Aeronautics and Space is reported to have said: “We have come to agree that this ‘thing’ cannot be scientifically proven.”

The mystery, therefore, runs on and on – and this particular video has resurfaced, despite controversy.

Is there any truth in the theory that aliens really do exist? Apparently so – according to an alien expert over 200 extra terrestrial species regularly visit Earth.

Meanwhile, UFO sightings in the North East of England have had alien enthusiasts convinced since earlier this year.
