The World UFO Day Organization declared July 2nd to be the official World UFO day. This day is dedicated to the existence of Unidentified Flying Objects. There are several reasons why this day is important. One of the first and foremost reasons is to raise awareness about the existence of UFO's and intelligent beings from outer space.
Also this day is used to encourage governments to make public their knowledge about sightings throughout the history. Many governments are believed to have gained exclusive information about UFO's through their military departments. A subject that still raises a lot of curiosity is the Roswell incident in 1947 when a believed UFO crashed in Roswell, New Mexico.
