Have you ever seen a unidentified flying object(UFO)?

the odds that we are alone in the universe? very slim. i've never seen one, or a "UFO", and I'd rather have the government deal with the first contact, but I believe their out there, wondering the same thing about us. i also think it's highly unlikely a more advanced form of life ,they must be if they have interstellar space travel, would come here to our little planet and run tests on us. most of those who have claimed to be abducted are full of it. besides, if they're so advanced, how is it that they "accidentally" get seen by humans? While some undoubtedly are more advanced, I bet there are also a lot of society's out there who are at our level, if not behind.
