  hi jamie! Thanks for the question!
  The answer is earth! It is the only planet that is known to have an oxygen atmposphere that we need to breathe, and the only one where liquid water is known for sure to exist! It’s the only planet where we can wander about without the need of a spacesuit.
  There is a reason why we are so suited to earth though – we evolved here to suit the earths environment!
