The Bible itself makes no statement about Earth's age, but various religionists have tried to infer the age from biblical narratives. The most famous and influential attempt was made more than three centuries ago by the Irish churchman James Ussher, Archbishop of Armagh and Primate of All Ireland, who summed the lifespans of the patriarchs listed in the Book of Genesis, refined that sum by making some theological assumptions, and deduced that the biblical god had created Earth on 23 October in the year 4004 BC. This result, which Ussher promulgated in 1650, has been printed as a margin-note in many editions of the Bible and has acquired the force of scripture among many fundamentalists.
