stars I was preparing to use my telescope In a clear night full of bright when I saw two bright lights traveling together very high up in the sky close to the stars...from the south to the north crossing the space and disappearing in a vertiginous speed but after a few minutes I saw them again coming back from the north to the south as if they were guarding the earth space, or perhaps preventing other races from coming in contact with humans on earth...The second night I saw them again and I could look at them with my binoculars and one of them show a tremendous super bright red white light as if was exploding, I was not the only one that saw that light as if was a huge explosion without sound. Then after that moment I only saw one traveling this time from east to west very fast. Third day I saw only one craft traveling crossing the sky so fast from different directions... my thought was that if I could see them without binoculars in clear view what size of their craft they must have been? In different occasions I saw a similar UFO craft crossing the Moon from up to all the way down in an incredible speed and other days I saw the same black craft crossing the Moon from right to left, and viceversa. I am incline to think that these UFO's and craft I saw this last time in Utah are nothing less than American UFO's living in the Moon or another planet...preventing the visit of other humans or other beings to visit or help humans on planet earth... No one can convince me otherwise!
