There's a small amount of radioactive carbon-14 in all living organisms.

This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.

those that form during chemical reactions without breaking down).

This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).

Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.We are told that these methods are accurate to a few percent, and that there are many different methods.Contrary to creationist claims, it is possible to make that determination, as the following will explain: By way of background, all atoms of a given element have the same number of protons in the nucleus; however, the number of neutrons in the nucleus can vary.An atom with the same number of protons in the nucleus but a different number of neutrons is called an isotope.If these dates are correct, this calls the Biblical account of a recent creation of life into question.
