About :

Are we alone in the universe? With over 100 billion galaxies in the observable universe and at least 500 billion planets in the Milky Way alone, don’t you think we should have found something by now? Even if a small percentage of those billions of planets were home to intelligent life, there should be tens of thousands of extraterrestrial civilizations out there. Yet, we haven’t seen a single one. Where is everyone? We keep wondering why it’s taking them so long to arrive. But what if I told you that even the friendliest of aliens could destroy our entire civilization forever?
