Water is the most common molecule in the universe that is a liquid and good solvent at a temperature in which organic chemistry is feasible.

Oils, alcohol, and some other molecules are liquid too at this temperature, but they are only metastable and are very rare in the universe. They break down into H2O, CO2, and CH4.

Some other common molecules and elements like H2, He, NH3, and CH4 are only liquid in extremely cold temperatures in which chemical reactions are extremely slow. Also, they are bad solvents.

Some other common elements like Fe are liquid only at high temperatures at which complex molecules don’t last for a long time. Also, they are bad solvents.

I remember my biology teacher making a big deal about how water happens to be both adhesive and cohesive. So it sticks to itself and other substances, which is why it forms drops (adhesion) and why it will travel up a napkin if one bottom corner is dipped in water (cohesion). These two properties make it possible for water to travel upward against gravity in plant life so that nutrients can get from roots to stems to leaves.

Imagine you have two pigments that you want to mix to get a nice color. If you try it mix them dry it wont be easy and the result will be quite bad, but with just a little bit of water those compounds can easily be dissolved and mix together nicely.

Now, life needs a whole bunch of substances to be constantly mixing and reacting with each other, and so it need a solvent. As to why water specifically? Well it’s largely available on earth and it can dissolve *a lot* of stuff, so you know, life “found a way” to use it.

It’s liquid, meaning molecules move freely past eachother but can also collide. In a solid they don’t move so nothing happens, in a gas there is too much space between them so they don’t collide often.

There aren’t many liquids at earths temperature, but on other planets they are definitely looking for life without water, but other liquids.

Water is also nice for any aquatic life in colder regions. Water being less dense as a solid isn’t too common, so if it was a different liquid, it would freeze, then sink to the bottom, forcing everything up as it keeps freezing, eventually freezing solid. When Water freezes, it insulates the liquid before
