Dating is not necessary to demonstrate that evolution is a fact.

Chronological sequence is all that is really required.

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.

Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

A few examples of such lies are presented at the very bottom of this page.For each dating or chronological method there is a link in the box at right to take you to that section of this page.There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.Hutton, a Scottish geologist, first proposed formally the fundamental principle used to classify rocks according to their relative ages.He concluded, after studying rocks at many outcrops, that each layer represented a specific interval of geologic time.Further, he proposed that wherever uncontorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.
