The CIA published a set of declassified documents dubbed to be part of its version of the “X-Files” last week just days before the show’s new mini-series aired in the U.S.

In its post on the official CIA website, titled “Take a Peak Into Our ‘X-Files,’” the agency selected 10 of those documents that it thought might intrigue fans of the TV show, noting that the CIA declassified hundreds of documents from the 1940s through the 1990s pertaining to investigations dealing with reported “sightings” of UFOs.

To help navigate the vast amount of data contained in our FOIA UFO Collection, we’ve decided to highlight a few documents both skeptics and believers will find interesting,” the post said. “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. We also pulled five documents we think his skeptical partner, Agent Dana Scully, could use to prove there is a scientific explanation for UFO sightings.”

The rest of the documents that were released mostly ranged from translations of foreign UFO-related articles to CIA memos actually admitting there were quite a few cases that the agency simply couldn’t explain, according to NBC News.

“Most of the documents concern CIA cables reporting unsubstantiated UFO sightings in the foreign press and intra-Agency memos about how the Agency handled public inquiries about UFO sightings,” another post on the CIA’s website explained.

Many fans of “The X-Files” took to Twitter to proclaim their astonishment, concerns and enthusiasm about the CIA’s public acknowledgment of its extra-terrestrial investigations.
