Here's a great graphic showing the amount of all water(including ices) on other Worlds and Moons in our Solar System, relative to our planet's total water volume. Guess what....Earth is NOT the top "Water World" by a longshot; giving more credence to the possibility of life existing elsewhere and that our planet is not the only geologically active body within the Solar System. The visual is from National Geographic Magazine.
Mining asteroids for minerals and outer solar system objects for ice has long been a theme of science fiction. One of my favourite novels set on the stage of such an interplanetary civilisation is "The World of Ptavvs" by Larry Niven, 1966.
Truthfully , it won't be much of a surprise when some form of life in this system beyond Earth is found. Even if it is 'single celled'. Using the term loosely due to the possibility extraterrestrial life may not even be 'built' with cellular structures.

You're welcome...I knew that many of the moons of our solar systems' gas giants held vast quantities of water; but I had no idea that some were equal or surpassing the Earth's water volume by such large margins. Truly mind boggling and the easily understood graphic put this into clear perspective; hats off to National Geographic Magazine. .

After realizing the vast amounts of "water worlds" in our solar system, I think life beyond Earth is a certainity.
You are only counting water on the surface. Most of the minerals in the crust and mantle have water in them. There is probably more water in the minerals in the mantle than on the surface.
