Once 14 C is produced, it combines with oxygen in the atmosphere ( 12 C behaves like 14 C and also combines with oxygen) to form carbon dioxide (CO 2 ). Because CO 2 gets incorporated into plants (which means the food we eat contains 14 C and 12 C), all living things should have the same ratio of 14 C and 12 C in them as in the air we breathe.

car·bon dat·ing • n. the determination of the age of an organic object from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.

Most people think that scientists can actually measure the ages of rocks, using a method called “radiometric” or “radioisotope” dating. More often, rocks are “dated” by the fossils they contain, based on a pre-existing belief in evolution. But even radiometric dating does not actually directly measure the age of something (there is no substance called “age”). It measures the amounts of certain radioactive substances. This information then has to be interpreted , based on certain beliefs.
