I dont think its a matter of life being so special. But planet earth being so special. Life could not exist on earth if...
- There was a slower rotation of the earth
- Faster rotation of the earth
- The earth was 2-5% farther from the sun
- Earth 2-5% closer to the sun
- A smaller earth
- A larger earth
- A smaller moon
- A larger moon
- More than one moon
- The earths crust thinner
- The earths crust thicker
- Oxygen/nitrogen ratio greater
- Oxygen/nitrogen ratio less
- More or less ozone
