Following a week of unprecedented political discussion surrounding alien existence, global conversation has exploded once again. Former President Barack Obama joked that aliens are “real” but that he’s never seen them and they aren’t locked away at Area 51. President Donald Trump responded by directing U.S. agencies to identify and release long-rumoured UFO and extraterrestrial files “because of tremendous interest.” The world is watching the skies - and asking who, or what, might be watching back.
