Tommy Moo: Why is liquid water necessary for life? Isn't this a paradigm? Of course a solvent medium is best for bringing together the ingredients necessary for the right chemical reactions to occur, so some form of liquid on the surface is likely necessary, but why couldn't there be an entire ecosystem that arises based on ammonia? It is a polar solvent, like water. Reactions might take longer at colder temperatures, but this would only mean that life would take a billion years to evolve to the same extent as 100 million earth years.

You are absolutely right, it doesn't necessarily have to be water.  Ammonia and water are both protic solvents and in fact life as we know it (from a biochemistry stand point) could have developed in either.  Our biochemistry is just much more efficient in water (the argument of cause-or-effect/chicken-or-egg can be left up to others).  The fact that both ammonia and water can donate and accept protons is the key.  In a similar fashion, there could even be a whole ecosystem based in ethanol; perhaps called fark.

Came here for the "10 ft difference and we'd die" reference. Leaving satisfied.
