Did you know that you can be a Christian, and believe that the earth is billions of years old?
Animals and humans who eat these plants take the Carbon-14 into their systems just as they would Carbon-12 Dioxide.
There is then a ratio of Carbon-14 to Carbon-12 in the bodies of plants, animals and humans which could be considered as fixed at the time of death.
The Carbon-14 dating method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.
He claimed that it was capable of dating animal, plant and human remains of fairly recent origin. As they say on Star Trek, we are all carbon based units.
Then, in another 5,730 years, a second decay period would occur, leaving one quarter of a pound.
The process would continue, halving the amount left every 5,730 years until, theoretically, nothing remained of the original pound.
Radiometric dating remains a reliable scientific method.

The topic of radiometric dating has received some of the most vicious attacks by young earth creation science theorists.
