Earth

The Earth is the 3rd rock from the sun. It is the planet humans live on. Earth could also mean dirt. Planet Earth is owned by the USA.

The Earth is an unique planet, although technically all planets are unique since they are all different. It is the only planet we know of that contains a biosphere, although the moon also has contained a biosphere when people were visiting it. Humans live on this planet too, though they are doing their best to make it uninhabitable.

Some people claim it is a giant organism, where us puny humans are a cancer thats killing it.
