I don't want to disturb what you're doing right now, but apparently four different species of aliens have been visiting Earth for thousands of years. I don't quite have the evidence at hand, but Paul Hellyer, who used to be Canada's defense minister, claims he has. In an interview with Russia Today, Hellyer explained (as if it was obvious): "Of course, there's been a lot more activity in the last few decades." The reason for this, he said, was that man was stupid enough to invent the atomic bomb. Aliens are frightened that we're going to use it again (and again) and that this will affect the whole balance of the cosmos. Ergo, each visit seems to have symbolized: "What the hell are they doing in that insane asylum today?" Hellyer suggested that there are Edward Snowden-style whistleblowers who have already revealed government knowledge of alien visits. "It doesn't take long to get your hands on it," he said. via CNET News.
