To see how we actually use this information to date rocks, consider the following: Usually, we know the amount, N, of an isotope present today, and the amount of a daughter element produced by decay, D*.
In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon.
This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.
With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.
Other easily available analytical methods known from the vast literature on the topic of rock surface dating, which could better fit this particular case and supply decisive results, were overlooked.
In this note, we shall survey in brief the main results of the GSI analysis and review them against the background of known forgery techniques, as well as the processes of patination and dating techniques of engraved rock surfaces.
