Clay appears to be a more fertile, composed of more minerals, but it may be the origin of life on Earth. In the simulation of ancient sea water, clay formed hydrogels-which are absorbed by a large amount The tiny space composition of the liquid (like a sponge). In the past billions of years, the chemicals that have been trapped in these spaces may have undergone complex reactions, which have led to the formation of proteins, deoxyribonucleic acids, and ultimately fine living bubbles. The hydrogel formed by clay may have restrained and protected the above chemical processes until the development of a cell membrane surrounded by living fine vesicles.
