However, human beings love to see factual precision, and we want to know how old something is.
Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.
Although relative dating can work well in certain areas, several problems arise.Three of the Carbon isotopes (C) are found in nature.The rest of the carbon isotopes are only of laboratory interest.Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.There are two techniques for dating in archaeological sites: relative and absolute dating.
