Planet Earth. Population: 1 We cannot understand how it happened. On September 1, 2019, it happened. We were all fine and from one moment to the next people began to suffocate. Little by little, the world fell into an astonishing silence. I survived that mysterious and catastrophic incident thanks to my father. When I woke up, I was faced with the horrifying panorama of millions of corpses. They were all dead. Soon after, I discovered that there were actually seven survivors left, and I joined them. Some dedicated themselves to investigating what had happened, the reason for the extinction of the human race; but they died in a strange way in a short time. Those of us left behind struggled to survive, but even so, the others also passed away after a few months. Now only I inhabit the world, I am the only one left on the planet ... Or at least, I believed.
