Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.
This standard content of C14 can then be used for wood not associated with a historically documented date.
What should Bible-believing Christians think about this apparent discrepancy?
Some believe trees are known to be as old as 9,000 years. A lot of people doubt this claim for various good reasons I wont go into here.
Yet the radiocarbon in these fossils, coals, and diamonds equates to “ages” of up to 55,000 years.
This is much older than the biblical time frame of earth history, which attributes most fossils and coals to the global Flood of Noah’s day, about 4,350 years ago.
In fact, 14C is forming FASTER than the observed decay rate.
This skews the 'real' answer to a much younger age.
