If only nuts think aliens are real, than NASA sure has lowered their standards. Wasn't there a press release just yesterday that they're going to search a number of planets for signs life? I think you're putting too much weight on fake conspiracies. There are real ones, and plenty of them. They just generally aren't as grand or well planned as the more famous ones. At least, the ones I know of in my city are that way, I know of a few people who were actually set up by the city government. These schemes are mostly powered through massive corruption, lot's of money with, perhaps, a sprinkling of stupidity. They get found out from time to time but it's hard to kick anyone out when you live in a one party town.
