The idea that we are not alone in this vast universe has obsessed man for a long time. It’s the stuff of countless movies, books, and research dollars. But despite the large number of reported sightings of unidentified flying objects (UFOs), there is still no concrete evidence that extra-terrestrials exist.
When someone reports a UFO, they usually describe it as having the shape of either a saucer, diamond, cigar or doughnut. This doesn’t come as any big surprise, because that’s how alien spaceships are usually depicted in science fiction movies.
