Atomic mass is a combination of the number of protons and neutrons in the nucleus.
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
If this claim is true, the biblical account of a young earth (about 6,000 years) is in question, since C dates of tens of thousands of years are common.1 When a scientist’s interpretation of data does not match the clear meaning of the text in the Bible, we should never reinterpret the Bible.
