and became famous for his genuine letters of the church. He is the Archbishop
of all Ireland and majorly impacted Reformation theology. He is best
known for his chronology research that concluded Adam was created in 4004
B.C. In reality, Ussher was a first-class scholar very involved in

Earth's crust by means of natural processes over geologic time. Hutton

atmospheric changes known as 'uniformitarian’s'. This paved the way for modern
geological science.</span>
