It’s the moment UFO fans have been waiting for -  the CIA has hand-selected some formerly top-secret files and photos to ‘prove’ extraterrestrials exist.

Sadly for extraterrestrial fans, the files are a bit lacking in alien autopsies and crashed flying saucers - but they’re a fascinating insight into the height of the ‘flying saucer’ era.

The CIA released the files - seemingly to coincide with the new X-Files episodes - provoking disbelief on UFO websites.

One report, entitled, Flying Saucers and dated 1 August 1952, says, ‘Less than 100 reasonably credible reports remain ‘unexplainable’ at this time. It is recommended that CIA surveillance be continued.

‘It is strongly urged, however, that no reports of CIA interest or concern reach the press or public.

The CIA said, ‘We’ve decided to highlight a few documents both skeptics and believers will find interesting.

‘Below you will find five documents we think X-Files character Agent Fox Mulder would love to use to try and persuade others of the existence of extraterrestrial activity.

Such documents often prove disappointing to hardcore UFO Fans, according to one expert.

Nigel Watson, author of the UFO Investigations Manual, said last year, ‘At least 10,000 UFO reports collected by the US, Project Blue Book, have been put online and many other governments have released their UFO files.

‘So we have an embarrassment of riches yet these have been largely ignored by UFO researchers, yet they could provide lots of information about types of sightings and their patterns over time and place.

‘The problem is alien saucers and body parts remain as elusive now as they always have been, and it frustrates the hell out of conspiracy mongers and ufologists.
