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.Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.The carbon-14 isotope would vanish from Earth's atmosphere in less than a million years were it not for the constant influx of cosmic rays interacting with molecules of nitrogen (N) into organic compounds during photosynthesis, the resulting fraction of the isotope 14C in the plant tissue will match the fraction of the isotope in the atmosphere.

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry. Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.Carbon-14 has a half-life of about 5730 years, and therefore it is used to date biological samples up to about 60,000 years in the past.Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
