Radiocarbon dating limitations

Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.It makes no sense at all if man appeared at the end of billions of years.

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.Obviously, this works only for things which were once living.Mixing and exchanges happen between the atmosphere and the biosphere until such time that equilibrium is established.Radiocarbon dating rests heavily on this assumption such that other sources of carbon 14 had, at first, not been considered nor accounted for. This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.

The AMS system itself is known to be capable of making measurements on single targets to a precision of better than 0.2% for the (super 14) C/ (super 13) C ratio and better than 0.1% for the (super 13) C/ (super 12) C ratio.

In routine operation, we measure known-age wood to a precision of just above 0.3%, including uncertainties in background and pretreatment.

Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.
