The only consistent way to interpret the geological record in light of this event is to understand that fossil-bearing rocks are the result of a massive global Flood that occurred only a few thousand years ago and lasted but a year.This Biblical interpretation of the rock record implies that the animals and plants preserved as fossils were all contemporaries.Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale.Even if they cannot provide a naturalistic mechanism, they appeal to the "fact of evolution," by which they mean an interpretation of earth history with a succession of different types of plants and animals in a drama spanning hundreds of millions of years.This is partly due to the legacy of the doctrine of uniformitarianism passed down from one generation of geologists to the next since the time of Charles Lyell in the early nineteenth century.Uniformitarianism assumes that the vast amount of geological change recorded in the rocks is the product of slow and uniform processes operating over an immense span of time, as opposed to a global cataclysm of the type described in the Bible and other ancient texts.Back in the 1940s, the American chemist Willard Libby used this fact to determine the ages of organisms long dead.

The carbon 14 present in an organism at the time of its death decays at a steady rate, and so the age of the remains can be calculated from the amount of carbon 14 that is left. The cells of all living things contain carbon atoms that they take in from their environment.

Carbon-14 is also passed onto the animals that eat those plants.

After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.
