It's the Headquarters of the Secret One-World Government
If you're into conspiracy theories with a truly grand sweep, Area 51 is a convenient place to pull all of the threads together. That's why some speculate that the test range is the logical place for the location of Majestic 12 [source: Cook]. The latter, if you buy the narrative laid out by an anonymous author on the conspiracy site Educate-Yourself.org, is a secret government committee that has been laboring in the shadows for more than six decades to work out an arrangement for a one-world government in which the planet would jointly be ruled by human and extraterrestrial elites.
MJ-12, as conspiracy junkies refer to it, supposedly started as a blue-ribbon panel of scientists and military leaders created by President Harry Truman in 1947, shortly after the crash of an alien spacecraft near Roswell, New Mexico. As the story goes, MJ-12 somehow eventually made contact with the aliens and brokered a meeting between them and President Dwight Eisenhower. That, in turn, resulted in a deal in which the U.S. government got extraterrestrial technology, in exchange for looking the other way when UFO crews mutilated cattle and abducted humans to conduct weird experiments on them [source: Jacobson].
