Furthermore, since God created the earth and everything in it in seven days, nothing else on earth existed before this time. We will attempt to examine this contradiction from both vantage points. Radiocarbon Dating Radiocarbon dating was developed by Willard Libby in 1948. At the same time, 14-C is continuously being produced in the upper atmosphere by a reaction involving cosmic radiation. Constant decay of 14-C is balanced by constant production.
Carbon is passed between atmosphere, oceans, and living things in a process called the Carbon Cycle.
In this way, the balance struck between 14-C and decay in the atmosphere is passed around the cycle. The cycle is stopped by death. When a plant or animal dies and is preserved, its exchange of carbon ceases. The half-life referenced above is defined as the time taken for half a raidoactive isotope to decay. Thus after a time of one half-life has elapsed, one half of the isotope will be left.
