Aliens Could Be on Their Way to Earth

The universe contains hundreds of billions of galaxies, trillions of stars, and even more planets. If even a small fraction of these planets are habitable, then the universe should be teeming with life. Yet, we see nothing but vast emptiness. Where is everyone else? The answer to this riddle could be as exciting as it is creepy. We may be early born before almost all other life, but soon this might change. Not only might aliens appear, but they could quickly surround us, starting an irreversible competition for the universe.
