In this second episode of a three-part series, George continues presenting The Arrow of Time. This episode examines the importance of chronology. Does the world have a beginning and an end? Basing themselves on the Bible, Early Church Fathers sought to date the divine Creation of the world (in 4004 BC), as well as to anticipate the Second Coming (perhaps in 800 AD). They tried to reconcile their hope for a better future with the disasters of their own day. After the Renaissance and Reformation, chronologies began to fan out – the world no longer seemed thousands of years old, but stretched back millions of years. Recent discoveries put the origin of life on Earth some 4 billion years ago.
