Carbon dating science
Hovind goes on to claim "This also means that plants and animals that lived in the past had less C-14 in them than do plants and animals today.Just this one fact totally upsets data obtained by C-14 dating." A study of plants of the past, using tree-rings, confirms a direct correlation between C-14 levels and the earth's magnetic field, over the last 8,000 years.
He does give an illustration of a candle burning, saying it would be like assuming the candle always burned at the same rate.
Sometimes, it is near zero, other times it is greatly increased.
Therefore over time, we could have reached equilibrium many times. Since the rate of C-14 production is far from constant, the theory that the earth is less than 30,000 years old based on equilibrium is unreliable.
Despite its limitations, carbon dating has proven to be an extremely useful way to determine the age of important archaeological discoveries, such as the Dead Sea Scrolls and the Iceman remains.
It has also given scientific weight to arguments surrounding controversial objects and their dates of origin.
