Carbon dating and the
In fact, 14C is forming FASTER than the observed decay rate.
This skews the 'real' answer to a much younger age.

The scientists who were trying to build the chronology found the tree rings so ambiguous that they could not decide which rings matched which (using the bristlecone pine).
by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.
This is only because it is well calibrated with objects of known age.
C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).
The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.
