![AMARGOSA VALLEY, NEVADA - JULY 21: A billboard advertising for a convenience store named the Area 51 Alien Center is 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.
