Geologists do not use carbon-based radiometric dating to determine the age of rocks. Just how old is that pretty little fossil? How far can you go back in time, and assume an accurate sample with carbon dating? Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.

The carbon clock is getting reset. Despite the name, it does not give an absolute date of organic material - but an approximate age, usually within a range of a few years either way. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. Sincescientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbona radioactive isotope of carbon.
