Personally, I believe most of the UFO sighting reported are hoax or questionable observation of other stuff (i.e. natural phenomenon or military tests of unreleased black op equipment). However I wouldn't discount all of them and believe it is possible (not probable) to have UFO and aliens.
Most other cultures think of ghost and devils instead of aliens and UFO. Americans tend to think of UFO and aliens. Wonder why?
