Water, and more precisely sea water, is the main ingredient in the recipe of life. Every form of life on Earth is constituted of one primordial yet complex element that we know as “the cell” — wether it contains a core protecting its DNA<ref name="dna">Desoxyribonucleic acid: the molecule carrying genetic informations of one cell.</ref> (eucaryotes like plants and animals) or no core and a free floating DNA<ref name="dna" /> (procaryotes like bacterias). What this cells contain and where they generally hang around is generally salted water. As life emerged and thrived in the Earth’s oceans, the chemical concentration of both the inside of cells and most fluids used by living beings (to convey nutrients or waste), are surprisingly close to sea water.
