That would be, like, "Earth". like, like, really?!
Earth is the only planet known to have life and liquid water.
The Earth is sometimes called the "Blue Planet" or "Water Planet" because it is the only known planet that has large amounts of liquid water. Water bridges the gap to life, so water makes it possible for the Earth to support life.
The goldilocks planet does not exist. It is an area in a planets orbit where water is liquid and life could exist. See related question.

Mars.
Water
Earth is the only planet known to have life and liquid water.
The habitable zone is that zone in which water is liquid. Without liquid water, life as we know it would not be possible.
there is NO living life on Mars b/c there is no liquid water on it.
It has a large quantity of liquid water.
Only planet to support life (known life that is) only planet with liquid water isn't a precise spherical shape
Water is necessary for life to exist, and since earth is the only planet known to have liquid water, it is the living planet
The question seems poorly worded, but Earth is the planet with liquid water on its surface.
Earth is the only known planet to have oceans of liquid water.
The Earth is sometimes called the "Blue Planet" or "Water Planet" because it is the only known planet that has large amounts of liquid water. Water bridges the gap to life, so water makes it possible for the Earth to support life.
Personally, I believe that the discovery of liquid water is so important is because all forms of life need water to survive. :-), Ri
