Has anyone ever seen a UFO?

Hi everyone, I want to ask you if anyone has ever seen an unidentified flying object? I want to know about their appearance, do they really exist and anything more that would be related to them. So, if anyone has any info on them, kindly share it.

The same here, it is indeed hard to say about their existence. There have been many discussions on this topic and it still goes on. There have been sightings on them and it has been reported on various places. For more information, you can browse the sources that hold information for them; one which I recently visited http://www.ufo-sightings-evidence.com/ which had good material on them.
