there are some real nut jobs out there who don't think about things before making conspiracy every where, in case you don't know, Area 51 is the most famous secret base in the world.
debate your views on it, I personally think those people who think aliens are there are nut jobs. why would they let such a secret be known world wide? lets say the government does have aliens, they would be in a base that is an actual secret, some where not on Google maps, some where under ground.
