Even the presidents of the United States have doubted what is really in the well-known Area 51 in Nevada.Former President Bill Clinton said that during his term he sent people to this iconic location to find out if it really housed aliens.“When he was president, he had a chief of staff, John Podesta, who loved science fiction, we did everything we could to find out everything about Roswell.And we also sent people to Area 51 because we wanted to make sure there were no aliens," Clinton said on CBS's The Late Late Show with James Corden.Bill Clinton refers to the Roswell case, when an unidentified object crashed on a ranch in New Mexico on July 2, 1947. Although the authorities claimed it was a weather balloon, this is the center of various conspiracy theories about alien life not disclosed to the public.Conspiracy theories claim that the alien technology found in this incident is in a hangar at Area 51.Clinton recounted that he sent Sandy Berger, his security adviser.What they found had more to do with technology that the United States does not want revealed than with aliens."I said, 'We have to figure out how we're going to deal with this because that's where we do a lot of our invisibility research, in terms of technology, we study how to fly planes that are not detected by radar and all that,'" he explained to Corden. .Clinton reflected: “So that's why they're so secretive (at Area 51).But there are no aliens that I know of."Area 51 is a US Air Force base that has been an enigma for years.This was officially acknowledged in declassified CIA documents in 2013.In 2019, a movement was sparked primarily through a Facebook event to invade Area 51.More than 2 million people put “attend” and 1.5 assured “being interested”.The total attendance did not reach the 2 thousand people who participated in festivals and meetings in nearby locations, but the air base was not invaded.
