AMARGOSA VALLEY, NEVADA – JULY 21: Billboards advertising for a convenience store named the Area 51 Alien Center are seen along U.S. highway 95 on July 21, 2019 in Amargosa Valley, Nevada. A Facebook event entitled, «Storm Area 51, They Can’t Stop All of Us,» which the author meant as a joke, suggested the attendees to meet up at this colorful tourist attraction before storming the highly classified U.S. Air Force facility on September 20, 2019, to address a conspiracy theory that the U.S. government is conducting tests with space aliens David Becker/Getty Images/AFP
