I've never seen them but deep inside I really want to believe.
Oh and here's something interesting. Stanley Fulham is said to be a Ufologist with an uncanny record of giving accurate UFO sighting predictions. The recent sighting in Moscow was said to be a prediction fulfilled. There's also a prediction (probably from Fulham) that extraterrestrials and the world leaders will meet soon. If this were to happen, I really hope we'd have a utopian future similar to Star Trek.
