The universe is so vast that we have still yet to understand just how gigantic it really is. The one thing we know for certain is that we are not really certain of it at all. And what continues to baffle the minds of both experts and civilians alike is the potential existence of other life forms outside of humans on Earth. For decades and even centuries, there have been strange occurrences that have left people totally perplexed – sightings of other worldly phenomena here on Earth and in the skies above. The only explanation has been that there is indeed life on other planets, and that they have frequently made their presence known to us. To learn just how wild these occurrences have been over the years, check out these top 10 most fascinating UFO sightings of all time.
North Yorkshire, England
In North Yorkshire, England in 1952, a silver disc was seen hovering in the sky for several days on end. It was witnessed by multiple people in various locations around the city, all reporting that the unknown object was completing strange maneuvers they’d never seen any other aircraft perform.

Rendlesham Forest, Suffolk, England
Back in 1980, members of the U.S. Air Force at an airbase in Suffolk, England reported strange lights in the Rendlesham Forest. They believed it to be an unidentified flying object, and was the size of a house. Later, it was released that radiation readings in the area were abnormal and there were strange tree markings as well.

Mount Rainier, Washington
In 1947, a pilot named Kenneth Arnold saw a series of UFOs near Mount Rainier. He saw approximately nine objects – and they were all flying at about 1200 miles per hour, which is twice as fast as any other aircraft has ever been known to fly. This sighting is known as one of the first UFO events that was widely reported on and gained attention across the world.
