Methods other than carbon dating

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.Far from being data, these dates are actually interpretations of the data.As discussed before, the assumptions influence the interpretation of the data.By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.

There are three main assumptions that must be made to accept radiometric dating methods.

These must be accepted on faith in uniformitarian and naturalistic frameworks.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.

Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.
