On and Off I keep reading in newspapers about scientist in NASA to have found traces(or they suspect it to be traces) of water vapour in atmosphere of some celestial object 200 light years way. Hmm...great news but what is the relevance? Water is absolutely necessary for our(read Earth's) survival, but that may not true for all the other life forms which I am sure, exists somewhere, out there. Then, why focus space exploration only in search of water alone? Isn't it like putting blinders on when you are in an expedition?
There could be a 'life' form which is superior/inferior to us and has a different set of requirements for its survival. What if it survives on breathing Nitrogen, Carbon-di-oxide or some element which we are not even aware of?
I am no scientist and I want to keep things rank basic. Educated opinion says that Universe is so huge that even Sun is a tiny dot in it. Think about Mother Earth which is even smaller. It will be so naïve for us to believe that life can survive only if there is water, oxygen, optimum solar energy, photosynthesis and the like.

Search for water has definitely got to do with 'colonising' the celestial body so that its livable for earthlings. This is seriously bad intent.
