For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years.

As time passes, a rock will have more and more Argon-40 and less and less Potassium-40.

Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element.

By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate.Like the tree rings, this method can be verified by comparison to historical records for weather, as well as to records of volcanic eruptions around the globe that left thin dust layers on the glaciers.Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall.These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years.As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.
