Hi, i'm quite new to this website and loves i truly love astronomy! I'm here creating this thread is to find out whether are UFO's true/false?....I have read books writing about UFO's sightings at certain skies of the earth but just not one in where i'm living now??? I'm not doubting the books written on UFO sightings but i wonder y UFO's only fly near the western countries but not at the other parts of the world??? (Does this shows that the planets of these unidentified space objects are nearer to the those countries?) If these sightings r true, does this mean "a friendly visit" or a visit to plan an invasion on earth???
