Carbon 14 dating false
After all, this what the archeologist guessed in their published books.
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.
So they tested some of the ring sequences by C14 to put the sequences in the 'right' order.
Once they did that they developed the overall sequence.
For instance, remnants of organic matter formerly held up as solid evidence of the most recent, large-scale global warming event some 40,000 years ago may actually date back far earlier to a previous ice age.
Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so - a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.
In fact, 14C is forming FASTER than the observed decay rate.
This skews the 'real' answer to a much younger age.
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.
