The plant, animal and human will each have about the same ratio of C-14 to C-12 as does the air.
The next question is: Where did the air get its C-14?
If a moving neutron enters a nitrogen nucleus, a proton comes flying out, and the nitrogen atom is changed to an atom of C-14. The constancy of C-14 in our atmosphere depends on the cosmic rays coming into the atmosphere at the same rate.He would give this bone a false date because of a false assumption.If the ratio of C-14 to C-12 was much less in the past for any reason, then false dates would be given to such fossils.Most of the carbon before the Flood would then be C-12.Suppose the scientist doing the dating did not know about the Flood.
Anything that was once alive or that was produced by a living thing can be dated by using the radiocarbon method of dating.
