Yes we will admit water mediates many reactions.
Water also plays a role in making all bioactive materials, bioactive. A raw protein, just off a ribosome, is not bioactive. Once it enters the water, which is everywhere, the organic nature of the protein create a water-oil effect; surface tension with water. If we shake Italian salad dressing; vinegar (water) and oil, it can become an emulsion; mixed uniformly. If we wait a few minutes the water and will oil separate. In the case of water and raw protein, the protein will bubbles up in the water, with the water packing the protein into its bio-active shape. You cannot replace water, with nay other solvent, since other solvents pack protein differently and these shapes are not bioactive.
All the organelles in cells are due to the water-oil effect. Like with water and oil, they like little bubbles combining to, make bigger bubbles. In terms of evolution, the water and oil effect was always there, and as the first protein formed, the water started pack them and even caused groups to combines. This is not random but due to the water and oil effect having a goal of minimal surface tension.
If you had a bunch of different random protein; Abiogenesis, at the shoreline, where the waves mix and the water separates and packs; cyclically, eventually you get stable organic clusters.
The DNA double helix and the RNA single Helix are also water dependent. DNA and RNA differ by one base. DNA has thymine and RNA has Uracil. The Thymine is more oily due to the extra -CH3 group, so the water packs it tighter; double helix. DNA and RNA also have a different sugar which also favors DNA as a double helix; water-oil effect.
The image that current evolution theory paints is too random, since the water and oil effect forces results, that are the same each time. I like evolution, but the random assumption is sophomoric, due to water and water and oil effect. Water has a sweet spots of minimal potential and since water is still the dominant phase in cells; majority material, evolution is about working its way to the sweet spots of water. There may be randomizing, along the way, but mostly to find the better ways to the sweet spots.
Water has other tricks up its sleeve.
