I have no way of proving it but I think that water is a necessity to any beginning of carbon based life. Its a special liquid that is polar, is durable (based on the H bonds holding the molecule together), and it's polarity can affect surface reactions of other molecules especially polymers and fatty acids and esters, as well as various linkages.
All evidence we have from this planet about the origins of life, seem to occur only in palludal and alluvial basins (ponds, lakes and streams)
We do see extremophilic archea, but even these exist in the water phases like steam and ice.
Sci fi books were written about silica based life and the more we look at that the more unlikely it appears.
