Thank you for your response to my challenge! In my opinion, "life" doesn't need water. For what we refer to as "living", sure they may do - but you never know. There may be life forms out there that find water poisonous, for example. There could very well be life on Venus too! Great article, nevertheless, and best of luck with the results!

I agree, it is perhaps possible for some organisms to exist completely without water. The reason it is said that water is necessary for life is it's role as a solvent for many chemicals that allow lots of crucial reactions to take place in solution. As far as I am aware there is no other liquid that can act universally as a solvent to so many important substances. In my opinion this is why water is one of the first requirements people look for when searching for extra-terrestrial life.
On the other hand, the possibilities with regards to space are endless! Perhaps life exists in a form that we simply cannot conceive.
