It is very naive to think that the universe is only capable of producing water-based life. Conditions are so varied that we can expect life based on completely different concepts, starting with a different chemistry, and with a different structure - maybe not cellular based. And that life would exhibit completely different properties: size, velocity, morphology, ... And everywhere you look, whether in sci-fi films, literature, and even serious research programs, they are looking for simmetrical bipeds, roughly our size, with minimal morphological differences, water and carbon based, moving and reacting roughly at our speed, etc. Very shortsighted.
