James Hutton MD (1726-1797) was a Scottish geologist, physician, naturalist, chemist and experimental farmer. He is considered the father of modern geology. His theories of geology and geologic time, also called deep time, came to be included in theories which were called plutonism and uniformitarianism. He is considered the father of geology for his uniformitarian theory of continuous geological change over millions of years. He proposed that river sediments, washed into the sea, formed new rocks through the effect of geothermal heat. These were then uplifted to form new continents. Hutton's views were attacked by religious figures as they disagreed with their view of a biblical Creation a few thousand years ago.
