The origin and the foundation of the earthly life
Origin and development of life Life began on earth more than 3000 million years ago. Since then single-celled creatures undergo the process of evolution so that the animals and plants that the number and type is very diverse. Based on the calculation of age of the oldest rock findings, the earth is thought to be 4.500 million years old. During the first 1,500 million years, the earth was not inhabited by a single living being. There is no certainty as to how life originally arose. Experts suspect that the early process of life involves water, acid, and other chemical elements; the inorganic chemical reacts and produces self-replicating molecules. The above chemical seeds are thought to originate from space through meteorite collisions or the sharing of light-induced chemical reactions. Early living creatures Life molecules evolved into simple single cell life forms, floating on the surface of the ocean. The oldest surviving evidence of life forms is the bacterial and algae fo
