In 1650, James Ussher, Anglican Archbishop of Armagh (Ireland), published a work on the calendar in which he dated the earth to have been created ex nihilo on the evening preceding October 23, 4004 B.C., based on his study of the chronologies in the Bible and corresponding historical events. He sought to reconcile his faith in Scripture with the fact that we live in a world of history. While today it may seem a bit odd that our planet is 6,013 years old, his attempt was part of a growing movement to reconcile faith and reason. Of course, the good archbishop gave precedence to faith.
Science has shown us that the earth is much older than that. Life on this planet has changed and evolved over billions of years, and the amazing diversity and complexity of life on earth should give us all pause to contemplate the forces that drive them. The fact remains: just because there are dinosaur bones older than "Adam and Eve" does not mean that the truth of the Book of Genesis is any less true. God still has a plan; He continues to carry it out; we are intimate cooperators with Him in that plan. There is no contradiction there. Faith and science should be compatible because they have the same Author.
So relax. Let Mr. Colbert soothe you:
