Space is all wet?

Water on Mars. Water on Mercury. Water on the Moon! Water on moons of the giant planets. Comets made of ice. Saturn's rings made of ice chunks...

Do you get the impression there's a heck of a lot of water in space? Seems like anything that has spent any time floating about in space has accumulated molecules of water (frozen, of course!) which was retained when it accreted to form all the above. "Water, water everywhere, nor any..."

Apparently, the idea that comets brought water to Earth is right, but not the whole story. All the rubble that came together to form the Solar System evidently contained water, too. (I guess as the Sun began to heat up, its water was vaporized and pushed back into space by solar wind, ready to be picked up by the next passing object...maybe even Earth! Among countless others, naturally.)

So, with water everywhere, wherever it is in liquid form it can dissolve stuff, as well as permit reactions energized by radiation to form stuff like amino acids, etc., then it sure looks like life could develop all over the place!
