Carbon fourteen dating
Since carbon-12 doesn't naturally decay while carbon-14 does, once a creature stops incorporating more carbon into its body, the ratio of carbon-12 to carbon-14 in its body begins to change, with less carbon-14 per carbon-12 as time passes.
Since creatures incorporate carbon-12 and carbon-14 into their bodies at about the same ratio as it occurs in the atmosphere during their lifetimes, by looking at the ratio in the atmosphere today and by comparing it to the ratio as it is found in the specimen we are examining, we are able to determine when the specimen stopped consuming more carbon-14 (i.e. This is, of course, assuming that we know how long it takes for carbon-14 to decay and that we know that the ratio of carbon-12 to carbon-14 in the atmosphere today is about the same as if was during the creature's lifetime.
Carbon-14 is radioactive, and has a half life of about 5700 years.
Plants get their share of carbon atoms from the atmosphere. It is seen that at any given point of time, the ratio of stable carbon and radiocarbon in the atmosphere, is almost same as the ratio of stable carbon and radiocarbon in living organisms like plants, animals, and humans.
The sample of the end result would be contaminated.
Hence, it would not be possible to determine the age of a sample accurately.
When cosmic rays collide with the atoms, it creates an energetic neutron, which, upon hitting a nitrogen atom (7 neutrons and 7 protons), creates a carbon-14 atom (6 protons and 8 neutrons) and a hydrogen atom (1 neutron, 0 proton).There is also the likelihood of the sample being contaminated with old or new carbon.For example, logs of woods cut from different trees were burnt in a fireplace.If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgment and spend eternity with God in heaven.
