Dear reader. I wish I could tell you that humanity survived. That zombies didn't invade the world. That us humans could have stuck together. That we wouldn't fight over political and economical matters. But that is not true. We didn't survive on Earth, and here I am, writing about it on Mars. Yeah, Mars was our only option. I don't think we will survive much longer. We have been here for 2 hours. All earth is full of zombies. The population of humans before the apocalypse was 7.8 billion. Now everyone except me and three others remain human. I better start the story from the beginning, shouldn't I?
