This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.

Accordingly, carbon dating carefully applied to items from historical times can be useful.

To derive ages from such measurements, unprovable assumptions have to be made such as: There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. For example, deeper rocks often tend to give older “ages.” Creationists agree that the deeper rocks are generally older, but not by millions of years.

Geologist John Woodmorappe, in his devastating critique of radioactive dating,[8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay.

C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.

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

A stronger magnetic field deflects more cosmic rays away from the Earth.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.
