Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon 12. But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: half of any sample of it decays into other atoms after 5,700 years.Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.Sedimentary rocks sometimes contain fossils formed from the parts of organisms deposited along with other solid materials.A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon-14 and a comparison between the ratio of carbon-12 to carbon-14 in a sample of the remains to the known ratio in living organisms. A technique for measuring the age of organic remains based on the rate of decay of carbon 14.
On the other hand, basing one’s ideas on the Bible gives a very different picture.
The Bible states that man was made six days after creation, about 6,000 years ago.
So a time-line of the world constructed on biblical data would have man almost at the beginning, not the end.

But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay.
