What isn't being discussed here is that if a planet is to have surface water, you have to fill up the internal part of the planet first with water before you will see any water on the surface. The water will percolate all the way down to the core. The core of the Earth has enough water to fill all the oceans on the surface. Strange forms of water ice are formed down there at 5000 degrees. Physics gets weird down there.
