In the 1950’s and 60’s Tinselgrad showed us a stream of alien monster movies, the basic idea of which was that some unknowable entities wanted to destroy Earth. The space ships would land, and the people would run away screaming to the scientists and soldiers “SAVE US! SAVE US!” Then in the 70’s and 80’s we got a series of movies showing aliens as benevolent beings. The space ships would visit Earth and people would run towards them shouting “SAVE US! SAVE US!”
Now the government has admitted that Unidentified Flying Objects (or “Unidentified Arial Phenomenon”) are real, that we don’t know what they are, what their purpose is, or how they do the things they do.
And the public’s reaction is “Meh.”
