Carbon 12 carbon dating
This would have resulted in an enormous amount of carbon-12 being released into the oceans and atmosphere.The effect would be not unlike opening a can of soda and having the carbon dioxide fizzing out.As with any radioactive isotope, carbon-14 decays over time.The half-life of carbon 14 is approximate 5,730 years.If you start with no carbon-14 in the atmosphere, it would take over 50,000 years for the amount being produced to reach equilibrium with the amount decaying.One of the reasons we know that the earth is less than 50,000 years old is because of the biblical record.
Carbon-14 is created in the upper atmosphere as nitrogen atoms are bombarded by cosmic radiation.In addition to the reasons mentioned in the previous paragraph, the flood provides another evidence that this is a faulty assumption.During the flood, subterranean water chambers that were under great pressure would have been breached.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.
First, for carbon-14 dating to be accurate, one must assume the rate of decay of carbon-14 has remained constant over the years.In fact, changing the environments surrounding the samples can alter decay rates.
