Earth as seem around 2010.

Earth is the third planet from the Sun and is the homeworld of the Earthlings. The rocky planet formed around 4.54 billion years ago about the same time as it's parent star along with 7 other planets. The Earth had only formed one moon 4.52 billion years ago when a planet slightly smaller than Mars is thought to have collided with the Earth ejecting material into space which under gravity's influence formed the Moon. This collision caused both the Earth and it's newly formed Moon to become molten ocean. The first life appeared around 3.6 billion years ago and up till the present date (2589 AD) has undergone 6 major extinction periods the most recent of which was caused by accidentally humans. Up until recently Earth had been in heavy pollution and suffered from severe overpopulation (11.5 billion). Today, Earth houses 8.4 billion humans and an additional 56 million in LEO and MEO. The 5 major nations of Earth are the American Union, the Sino Alliance, the Euro-Australian Republic, the Cascade Federation, and the African Nation. Earth currently houses 2 intelligent species: Humans and Dolphins. Earth is the only planet in the Solar System known to currently have intelligent life forms and one of only three worlds in the Solar System known to currently carry life: Earth, Europa, and Titan. Till today no ancient Sapient2 settlements have been discovered on Earth. This is likely because of Earth's gravity which is much higher that most of the worlds colonized by Sapient2.
