During the flood, subterranean water chambers that were under great pressure would have been breached.This would have resulted in an enormous amount of carbon-12 being released into the oceans and atmosphere.The carbon-14 that results from the reaction caused by cosmic radiation quickly changes to carbon dioxide, just like normal carbon-12 would.Plants utilize, or “breath in” carbon dioxide, then ultimately release oxygen for animals to inhale.
After death, the carbon-14 would begin to decay at the rate stated above. The accuracy of this method, however, relies on several faulty assumptions.
The second faulty assumption is that the rate of carbon-14 formation has remained constant over the years.
There are a few reasons to believe this assumption is erroneous.
To be grammatically crass, this ain’t necessarily so.
Live mollusks off the Hawaiian coast have had their shells dated with the carbon-14 method.
Carbon-14 is created in the upper atmosphere as nitrogen atoms are bombarded by cosmic radiation.
