Earth

Earth is the third planet in the Solar System and, until 2026, the only planet known to humans that hosted life. Its position in the Solar System sits perfectly in the habitable zone, making it the ideal place for life to evolve.

History
It formed with the Solar System about 4.5 billion years ago, when a cloud of dust and gas collapsed and surrounded the young Sol in a large disk. Out of this disk formed the eight planets, including Earth. About a hundred million years later, a smaller planet collided with Earth, creating a ring system that eventually formed Luna.

Humans, or more importantly, Homo Sapiens, appeared on the vast continent of Africa about 200,000 years ago. They were hunter-gatherers for thousands of years, crafting tools and weapons and migrating to new regions of the planet. Beginning in the 1800s, the Industrial Revolution began, with factories burning fossil fuels and pumping more and more carbon dioxide into the atmosphere.

The 20th Century was marked by bloodshed and huge advances in technology. Two superpower nations fought for world dominance, costing millions of lives through proxy wars. In 1962, these nations pushed the world to the brink of all-out nuclear war, and by 1969, one of them landed the first humans on Luna.

Starting in the early 2020s, private space companies and national space agencies from mainly the United States of America and the People's Republic of China, began a new space race, aiming to build Luna bases and a colony on Mars. Thanks to this competition, there is a huge presence of humans in space, including a terraformed Mars, floating cities on Venus and mining stations throughout the entire Solar System.

The effects of climate change were reversed in 2120, ending nearly a hundred years of environmental chaos. In 2134, a peace agreement was signed and the Democratic Republic of Humanity was founded.
