Pièrre La Place imagined an indefinite but very long history.And Jean Lamarck also proposed long ages.11 However, the idea of millions of years really took hold in geology when men like Abraham Werner, James Hutton, William Smith, Georges Cuvier, and Charles Lyell used their interpretations of geology as the standard, rather than the Bible.
In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.
This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.
Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.
The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.
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.
After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.
If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.
When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.
Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.
Another expectation is that there should be some discrepancies about the age of the earth among people as they scattered throughout the world, taking their uninspired records or oral history to different parts of the globe.
