#28: Area 51
Few regions in the United States are as mysterious as Area 51. While we don’t truly know what goes on there, we do know that it is a secret military installation that conducts highly classified activities. But that lack of insight has not stopped some from forming various theories about what this military area is really there for.
Many are under the assumption that Area 51 is a place where the United States conducts experiments on lifeforms from outer space. While others have little to no proof that we have ever been visited by aliens at all, these theorists are convinced that there are some living in our country at this very moment.
