However, evidence indicates that the opposite is true.Experiments have been performed using the radioactive isotopes of uranium-238 and iron-57, and have shown that rates can and do vary.There are a few reasons to believe this assumption is erroneous.The industrial revolution greatly increased the amount of carbon-12 released into the atmosphere through the burning of coal.Carbon has a weight of twelve atomic mass units (AMUs), and is the building block of all organic matter (plants and animals).A small percentage of carbon atoms have an atomic weight of 14 AMUs. Carbon-14 is an unstable, radioactive isotope of carbon 12.As scientists will often claim something to be millions or billions of years old (ages that do not conform to the Biblical account of the age of the earth), Christians are often left wondering about the accuracy of the carbon-14 method.

First, for carbon-14 dating to be accurate, one must assume the rate of decay of carbon-14 has remained constant over the years.Also, the atomic bomb testing around 1950 caused a rise in neutrons, which increased carbon-14 concentrations.The great flood which Noah and family survived would have uprooted and/or buried entire forests.This carbon-14 dioxide then ends up in humans and other animals as it moves up the food chain. Libby introduced the carbon-14 dating method at the University of Chicago.There is then a ratio of carbon-14 to carbon-12 in the bodies of plants, humans, and other animals that can fluctuate, but will be fixed at the time of death. The premise behind the method is to determine the ratio of carbon-14 left in organic matter, and by doing so, estimate how long ago death occurred by running the ratio backwards.
