This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years.

Anything over about 50,000 years old, should theoretically have no detectable C.

Overall, the energy of the Earth's magnetic field has been decreasing,[5] so more C is being produced now than in the past.

This will make old things look older than they really are.

We will deal with carbon dating first and then with the other dating methods.

Carbon has unique properties that are essential for life on Earth.

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.

However, even with such historical calibration, archaeologists do not regard C produced and therefore dating the system.

The amount of cosmic rays reaching the Earth varies with the sun's activity, and with the Earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy.

It does not give dates of millions of years and when corrected properly fits well with the biblical flood.

There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks.
