Earth is the third farthest planet away from the sun. Earth is my favorite planet because I live in it. Earth holds billions of people and its the only planet with oxygen. Earth is the only planet with life forms. Life forms is what makes Earth so important because with out us it would just be any normal planet. One of the reasons we even exist is becasue Earth has water and oxygen. Not only that but we have diffrent seasons becasue its not that close nor that far from the sun. Earth is also the only planet in this solar system that has water on its surface.
