Is that how it works in your mind? Buzz Aldrin sees something he can't identify, and that's enough to you to substantiate the contention that visitors from distant space somehow alter the laws of physics, all so that they can examine the inhabitants of a completely ordinary world at the fringe of the galaxy?
seriously though, astronauts have been seeing ufo's since the space program began. because, frankly, when you're exploring new territory, you can't always identify everything immediately.
