I always thought this was a flawed way of thinking. Yes, liquid water is key to OUR life, and life we observe here on Earth.
But who's to say water is essential to all life? There could very well be organisms on other planets that require other elements and compounds, but not water.

With our current know how, that is not how biology works. If what you are describing were plausible, Mars, Titan, etc would have strange life on them that adapted to the surrounding chemical elements of those worlds.

I'm thinking hypothetical life on Venus utilizes sulfur in similar ways Earthkins use oxygen. They breath vaporized elemental sulfur, exhale carbon disulfide, and drink, and bathe in, hydrogen sulfide liquefied under tremendous pressure.
The whole planet just stinks.
