Clay appears to be a poorly fertile mixture of multiple minerals, but it may be the origin of life on Earth. In the simulation of ancient seawater, clay formed hydrogels-made up of a large amount of absorbable liquid The tiny space composition (like a sponge). In the past billions of years, the chemicals that have been trapped in these spaces may have undergone complex reactions, resulting in the formation of proteins, DNA. and various systems that eventually produce living cells. The hydrogel formed by clay may play a role of restraint and protection for the above chemical processes until the development of a cell membrane that envelops living cells.
