If water exists, does that mean life (in some form) will exist? We know there are microbes and such which live in extreme conditions on this planet, though some water sources are too alkaline for life to exist. But if the water temperature is moderate, shouldn't something eventually evolve to live in that water regardless of other conditions such as higher gravity/pressure/radiation/etc?
Given that stars are fusing Hydrogen into Helium, Lithium and Oxygen etc., and water is 2H's and 1O, there is a lot of water in the Universe.
There is H2O on every planet within our Solar System, but complex life is only on one.
It takes much more than water to make life be able to stick around and evolve. Take Mars for example. Mars seems to have had oceans of water, but for the most part it evaporated back into the heavens. What didn't is bound up by other processes internal to the planet. Think water a
You will likely need other elements too (life as we know it requires, minimally, at least hydrogen, oxygen, carbon, nitrogen, and phosphorous.. plus most likely sulfur, sodium and magnesium too). And then, it needs the ability for those elements to mix (likely in isolation) in a combination of various different conditions.
No, probably not. Water in itself is a *very* common molecule in space and it can occur in wildly unhospitable conditions. And, of course, even if the physical conditions are somewhat sane, water is hardly the only thing you need for life.
There is at least traces of water pretty much everywhere in there solar system, including the sun itself (http://solar-center.stanford.edu/sunwater.html). As far as we know, there's life only on Earth in this system.
