Example of carbon dating

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).

First of all, it's predicated upon a set of questionable assumptions.THE AMERICAN HERITAGE® DICTIONARY OF THE ENGLISH LANGUAGE, FIFTH EDITION by the Editors of the American Heritage Dictionaries.Copyright © 2016, 2011 by Houghton Mifflin Harcourt Publishing Company.The ratio can further be affected by C-14 production rates in the atmosphere, which in turn is affected by the amount of cosmic rays penetrating the earth's atmosphere.The amount of cosmic rays penetrating the earth's atmosphere is itself affected by things like the earth's magnetic field which deflects cosmic rays.And finally, this dating scheme is controversial because the dates derived are often wildly inconsistent. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.

For example, "One part of Dima [a famous baby mammoth discovered in 1977] was 40,000 RCY [Radiocarbon Years], another was 26,000 RCY, and 'wood found immediately around the carcass' was 9,000-10,000 RCY." (Walt Brown, In the Beginning, 2001, p. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible.

We have to assume, for example, that the rate of decay (that is, a 5,730 year half-life) has remained constant throughout the unobservable past.

However, there is strong evidence which suggests that radioactive decay may have been greatly accelerated in the unobservable past.

Volcanoes spew out CO which could just as effectively decrease the ratio.

Specimens which lived and died during a period of intense volcanism would appear older than they really are if they were dated using this technique.

The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.
