They are then able to calibrate the carbon dating method to produce fairly accurate results.
"This attitude is clearly reflected in a regrettably common practice: when a radiocarbon date agrees with the expectations of the excavator it appears in the main text of the site report; if it is slightly discrepant it is relegated to a footnote; if it seriously conflicts it is left out altogether." (Peter James, et al. It is for specimens which only date back a few thousand years. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.
Anything beyond that is problematic and highly doubtful. 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.
The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.
So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.
Carbon-14 has a relatively short half-life of 5730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5730 years due to radioactive decay.
By about ten half-lives, or 58,000 years, the amount of carbon-14 left in the fossil is very little- about 1/1000 of the original number of carbon-14 atoms in the fossil.
Some chemical elements have more than one type of atom. Carbon has two stable, nonradioactive isotopes: carbon-12 (12C), and carbon-13 (13C).
In addition, there are trace amounts of the unstable isotope carbon-14 (14C) on Earth.
So, using carbon dating for fossils older than 60,000 years is unreliable.
