It makes no sense at all if man appeared at the end of billions of years.
We will deal with carbon dating first and then with the other dating methods.
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years.
After the organism dies it stops taking in new carbon.
Carbon has unique properties that are essential for life on Earth.
Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
Animals and people take in carbon-14 by eating the plants.Obviously, this works only for things which were once living.It cannot be used to date volcanic rocks, for example.One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.So, we have a “clock” which starts ticking the moment something dies.
Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science.
