Earth: Difference between revisions

Earth is the home planet of [[Human]]s, it consists of seven continents. It is home to a wide array of different creatures. Earth's history goes back as far as about 4.6 billion (US Billion) years ago when the planet first formed. The first single celled organisms appeared about 3.5 billion years ago, and eventually began to evolve into more and more advanced creatures. A certain species of exceptional intelligence, humans or ''Homo Sapiens Sapiens'', evolved about 150,000 to 200,000 years ago; they began building civilations that far surpassed what other animals could create. Several centuries after they became a spacefaring race, humans encountered a collective of intelligent, hostile extraterrestrials known as [[the Covenant]]. Thus begins the story of Halo.

The Covenant originally had no knowledge about humanity's home world, mostly thanks to the development of the [[Cole Protocol]]. Sometime between the events of Halo and Halo 2, the Covenant eventually discovered Earth's location. The [[Prophet of Regret]] led a small invasion force, but was surprised to find out that it was the humans' homeworld. At the end of Halo 2, the Covenant had eventually began a full-scale invasion of Earth, and have completely overrun in Africa by the beginning of Halo 3.
