Creationists have long insisted that the main evidence for evolution — the fossil record — involves a serious case of circular reasoning.

That is, the fossil evidence that life has evolved from simple to complex forms over the geological ages depends on the geological ages of the specific rocks in which these fossils are found.

The atoms of some chemical elements have different forms, called isotopes.

These break down over time in a process scientists call radioactive decay.

Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.

Each isotope is identified with what is called a ‘mass number’.The rocks, however, are assigned geologic ages based on the fossil assemblages which they contain.
