We started out as primitive nomads that hunted for their food with stone tools, and lived in caves. And within a less than a few dozen Millennia we've built giant structures that rise above the clouds, Planes made of metal that fly with ease, and electronic devices that enable us to talk to people across the world in real time. Every innovation and discovery that we've made, every feat that humanity has achieved were done so in times of violence, disease, and political strife. A simple glance at our history shows that we as a species are capable of doing great things despite our own flaws; I doubt we're doomed to die out on this little rock of ours.
