Carbon dating example problem
The formation of carbon-14 increases with time, and at the time of creation was probably at or near zero.
Since carbon-14 is radioactive, it begins to decay immediately as its formed.
The carbon-14 that results from the reaction caused by cosmic radiation quickly changes to carbon dioxide, just like normal carbon-12 would.
As with any radioactive isotope, carbon-14 decays over time.
The half-life of carbon 14 is approximate 5,730 years.
This would decrease the release of carbon-12 to the atmosphere through the decay of vegetation.
Third, for carbon-14 dating to be accurate, the concentrations of carbon-14 and carbon-12 must have remained constant in the atmosphere.
As scientists will often claim something to be millions or billions of years old (ages that do not conform to the Biblical account of the age of the earth), Christians are often left wondering about the accuracy of the carbon-14 method.
