Currently evolutionary geology explains the fossil record as the result of slow processes and change occurring over long periods of time. However, an increasing number of rock formations and fossil occurrences previously interpreted within such an evolutionary framework must be reinterpreted as the result of rapid, or even catastrophic, processes operating on a different time scale.

Fossils speak of catastrophic burial by water in many areas of the world, thus contradicting the uniformitarian model. A growing number of modern geologists concur with this view, although they may not accept the theory of a universal flood. Those of us who rely in the biblical story of a universal flood find in the fossil record abundant evidence that the surface of the earth once experienced the convulsions of a catastrophic destruction.

How can we accommodate the paleontological record with Scripture? If our approach to science is as it should be, we can acknowledge that there are still many unanswered questions for all sides, and we should have no fear of deeper investigation in science the data are not all in.

Frequently press reports describe the finding of bones and fossils of animals that existed millions of years ago. As a Bible-believing Christian and a creationist, my impression is that they can’t be that old. But I’m not sure. How can scientists determine the age of those specimens? How reliable are their dates?
