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.

Let’s do a rough calculation to show how this works.
The age of the earth can be estimated by taking the first five days of creation (from earth’s creation to Adam), then following the genealogies from Adam to Abraham in Genesis 5 and 11, then adding in the time from Abraham to today.
Floyd Jones4 and a much earlier book by Archbishop James Ussher5 (1581–1656). The misconception exists that Ussher and Jones were the only ones to arrive at a date of 4000 B. Jones6 lists several chronologists who have undertaken the task of calculating the age of the earth based on the Bible, and their calculations range from 5501 to 3836 B. Because of this, the Septuagint adds in extra time.
Though the Samarian and Masoretic texts are much closer, they still have a few differences.
The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.
Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.See table 3.8 Using data from table 2 (excluding the Septuagint calculations and including Jones and Ussher), the average date of the creation of the earth is 4045 B. This still yields an average of about 6,000 years for the age of the earth. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.1 - Department of Geosciences, 2 - Department of Physics, University of Arizona, Tucson, Arizona 85721, USA 3 - Research Laboratory for Archaeology and History of Art, University of Oxford, Oxford, OX1 3QJ, UK 4 - Institut für Mittelenergiephysik, ETH-Hönggerberg, CH-8093 Zürich, Switzerland 5 - Lamont-Doherty Geological Observatory, Columbia University, Palisades, New York 10964, USA 6 - Research Laboratory, British Museum, London WC1B 3DG, UK Very small samples from the Shroud of Turin have been dated by accelerator mass spectrometry in laboratories at Arizona, Oxford and Zurich.As Controls, three samples whose ages had been determined independently were also dated.Using other people’s research or ideas without giving them due credit is plagiarism.
