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.What methods do they use and how do these methods work?
An “isotope” is any of several different forms of an element, each having different numbers of neutrons.
The illustration below shows the three isotopes of carbon.
Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.
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.
Carbon-14 is mostly used to date once-living things (organic material). Carbon-14 is constantly being added to the atmosphere.
