Roswell, New Mexico, without a question, is the spot on Earth that best demonstrates that humans are not the only life on the planet.
This is because there were several claims of UFO sightings in the area in July 1947.
Many people believe that the object, or whatever it was, fell close to Area 51, the US Air Force Base.
It is certain that several witnesses found mysterious debris and what may have been the remains of a spaceship. These theories were all based on the idea that aliens from other planets had come to Roswell.
