I have been wondering why government might want to cover up the existence of aliens but can't really understand what would be in it for them. Suppose a government has learned that another world exists somewhere out there. Why cover it up? What is to be gained from a cover up?
I can understand that religions might have to adjust, but how else can the knowledge of alien existence be threatening?
