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.The procedures used are not necessarily in question. The secular (evolutionary) worldview interprets the universe and world to be billions of years old. The use of carbon-14 dating is often misunderstood.
So we should never think it necessary to modify His Word.
There are two main applications for radiometric dating.
One is for potentially dating fossils (once-living things) using carbon-14 dating, and the other is for dating rocks and the age of the earth using uranium, potassium and other radioactive atoms.
If this assumption is not true, then the method will give incorrect dates. If the production rate of C in a specimen difficult or impossible to accurately determine. Willard Libby, the founder of the carbon-14 dating method, assumed this ratio to be constant.
His reasoning was based on a belief in evolution, which assumes the earth must be billions of years old.
