Isotope decay dating
This assumption is backed by numerous scientific studies and is relatively sound.
However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.
Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.
Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.
As you learn more about chemistry, you will probably hear about carbon-14. C-14 is considered an isotope of the element carbon.
While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.
