Earth

In the Spore universe, the planet Earth is an Easter egg. Earth, along with other planets from the real life Solar system, can be found in the game. Once a player finds Earth, they are rewarded the "Manifest Destiny" Achievement. If a player chooses to destroy Earth with the Planet Buster, they will also achieve the "Oh the Humanity!" achievement. Earth is uninhabited by default.

About
Strangely, Earth has a Terrascore of 1 (High Atmosphere) in Spore and turns a brown-red color when it reaches a terrascore of T3. Many different interpretations have been formed by players to explain this, ranging from a reference to global warming to a general comment that, despite being the origin of humankind, Earth is not necessarily the best planet to harbor life in the universe. A common explanation also suggests that Spore is based before the age of mankind, millions of years in the past, before Earth fully became an inhabitable planet, which may involve the theory that aliens visted Earth millions of years ago. A far more likely answer is that humans are extinct on earth or left due to inhospitable conditions. This would explain the modern continental positions. However, since no confirmation on these views has been provided by the game creators, the possibility that this was simply a developer's oversight remains. The proportions of Earth are surprisingly small, with many small countries such as the UK or Ireland are shown as being the size of an average spaceship, however this is due to the game's processor and engine, it should also be noted that Earth is the same size as other terrestrial planets in Spore.

In addition, when the atmosphere is increased to make Earth T0, many of Earth's continents (including South America, parts of North America, much of Europe, and Australia) become flooded, again prompting some players to cite this as a reference to global warming. The only way to make Earth T3 without flooding it is to use the Staff of Life, necessary if the player wishes Earth to remain the same.

When Spore Galactic Adventures was released, Maxis made a template of Earth for adventure makers. Designed using USGS topographic maps, this replica of the Earth is perfect for creating your own custom made, realistic Earth adventures! Created by MaxisKate.

Colonizing Earth
If you want to colonize the planet, it seems like the only locations to build a colony without mutilating the terrain too much is Northern Asia or Antarctica, although there have been reports of very low or no terrain manipulation if placed in Africa or America from some gamers. Earth is usually a yellow spice planet, but can have green, pink or purple spice in some cases.

It is suggested that before you depart your home system, to buy lots of Bio-Protectors, Bio-Stablizers, and Uber turrets in case you want to colonize all of Sol and have high security. Make sure to ally with empires near Sol so they don't attack.

For some reason, you aren't allowed to place a monolith on Earth. However, occasionally a tribal species develops there, like on any other planet. It is not yet known if they can develop further, as cities and colonies would severely distort the landscape.

Steve
If you make it to the Galactic Core, Steve will give you the Staff of Life. He also mentions the "third rock from Sol," also known as Earth. Though he mentions a "free breakfast and presentation," if you do go to Earth there will be nothing new there.

Trivia
Some planets other than Earth (with normal names) can have the same terrain as Earth.
