evidence: Footage taken from the International Space Station's live feeds and widely shared on Reddit showed some unusual groupings of mysterious lights, seemingly floating by the orbital outpost like something out of a science fiction movie. "Can someone please explain what I just saw on the ISS YouTube live feed?" Redditor tyrannosnorlax asked on the forum. But as it turns out, the UFO hypothesis couldn't have been further from the truth. The lights turned out to be coming from human activity down on Earth, rotating below the space station — a simple mistake that, fortunately, turned into a learning experience for everybody involved.
