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.
The truth is, carbon-14 dating (or radiocarbon dating, as its also called) is not a precise dating method in many cases, due to faulty assumptions and other limitations on this method.
It cannot be applied to inorganic material such as stone tools or ceramic pottery.
The technique is based on measuring the ratio of two isotopes of carbon.
As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14).
