The first cells evolved in a watery environment so all the chemistry of life is based on it. H2O is also a somewhat odd molecule. Very polar (+ and – charged parts), neutral and capable of interacting with acidic and alkaline molecules and very stable. The polarity means that in the liquid state it forms clusters of molecules so the boiling point is much higher than you would expect from the periodic table – compare to H2S, NH3, HF, all gasses at room temperature.
