Earth as the only planet which life exist

Earth’s conditions are ideal for life.

1. Liquid water and all the other requirements for life exist on Earth. Temperature is just right for liquid water to remain.

2. The atmosphere of Earth is a complex system which is made up of Nitrogen, Oxygen, Argon, Carbon Dioxide and water vapor. This structure and continuous process of the atmosphere control the life on Earth. Life is also affect atmosphere both its variation and stability.

3. The atmosphere contain right amount of oxygen.

4. Earth is the only planet where gaseous oxygen is found. Because Earth has plants that do photosynthesis. There’s no other natural process that will put significant amount of oxygen in to a planet’s atmosphere.

5. But we does not mean that to exist life in any planet need to have oxygen.

6. Ozone layer of atmosphere is thick enough to protect life from harmful radiation and small objects from space.
