Flying saucers are not recognised as real. How can we see a real flying saucer ?."Everything hinges on the matter of evidence. On so important a question of UFOs, the evidence must be airtight. The more we want it to be true, the more careful we have to be. No witness's say-so is good enough. People make mistakes. People play practical jokes. People stretch the truth for money, attention or fame. People occasionally misunderstand what they're seeing. People sometimes even see things that aren't there.
