Water most likely basis for complex ecosystem development

The assumption that alien biochemistries probably require liquid water may seem a little Earth-centric. But given the chemical possibilities available from the most abundant elements in the universe, even an alien scientist with a different biochemistry would probably agree that a water-solvent-based biochemistry is quite likely to occur elsewhere in the universe and might well be the most likely foundation for a complex ecosystem in which intelligent life could develop.
