This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.Rocks being tested could have been contaminated by other sources of carbon.The amount of carbon in a rock tested today would be tainted because of the amount of carbon from the burning of coal and oil over the past 100 years.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.
