Hutton (June 3, 1726 - March 26, 1797) is considered to be the father of modern geology. He is accredited with proposing that observed geologic processes have been occurring at a uniform rate since the creation of earth, also know as the theory of unconformities. This led to his controversial suggestion that the earth is incredibly old. Hutton began to notice geologic processes on his land
