Theoretically, Creationism remains workable within a wide range of age estimates.
Scientists have proposed numerous age estimation methods.
Implicit in the Conventional Radiocarbon Age BP is the fact that it is not adjusted for this correction.
In this page, we consider natural reservoir variations and variations brought about by human interaction].
By the way, it is important to understand that most rock strata “dates” were actually assigned long before the first use of radioactive age estimating methods in 1911.
The Carbon-14 age estimating method is, at best, only useful for estimating the age of things that are thousands of years old, not millions or billions.
A CRA is derived using an age calculation based upon the decay corrected activity of the absolute radiocarbon standard (1890 AD wood) which is in equilibrium with atmospheric radiocarbon levels (as mentioned previously, 1890 wood is no longer used as the primary radiocarbon standard, instead Oxalic Acid standards I and II were correlated with the activity of the original standard).
