Do UFO's really exsist or are they just a figment of the imagination?

Question by cowgirl87_87: Do UFO's really exsist or are they just a figment of the imagination?
There have been many "sightings" of UFO's or strange lights but none have really been proven( i.e. The Pheonix lights in '97). So is it just a government cover-up, imaginary or do they really exist?
