Ufos are fake or not?

The Ufos are one of the most famous themes of the last years, there al la lot of persons who say that they have seen not identifay objects in the sky. We have a lot of photographies where we can see flying objects that apear like a plate. We have studies demostrating that the ufos are not fake, but they don't be realy 100% reliable. In my point to view there are no ufos and I'm never gona belive them until I see one with my eyes
