The term biogenesis was coined by Henry Charlton Bastian to mean the generation of a life form from nonliving materials, however, Thomas Henry Huxley chose the term abiogenesis and redefined biogenesis for life arising from preexisting life.[3] The generation of life from non-living material is called abiogenesis, and occurred through chemical and molecular evolution over millions of years.[4][5][6][7][8]
