The ocean is like the human brain. It is vast, expansive, wide, has a high ratio of depth-volume : surface area, has sections, is compartmentalized, is complex infinitesimally yet simplistic afar. It is elemental, powerful & dangerous. It's only constant is change and that change is instantaneously constant. It is built on waves, high and low. It thrives on change, ebb and flow. It wants to thrive, let it glow. It wants to change, let if flow.
The parent constituent of the ocean is water. Water is shape less, formless, made up of the two building blocks of evolution, hydrogen and oxygen. It is now a compound that existed through billions of years of natural selection and eventual evolution. It is the holy grail of survival for animals and plants. It is invaluable when united & when broken apart, releases two molecules which are the root of life formation and sustainance. It is one of the most important compounds and individually, molecules.
