Radiocarbon dating the earth site not updating
The logic for the theory is as follows: 1) The Bible reveals the age of the earth to be somewhere around 6,000 years.2) Since the earth is only 6,000 years old, the entire group of life forms represented in the fossil record (save the most recent fossils) existed at the same time and were all buried together in the world-wide biblical flood.
In creating their C model, that premise is used as the foundation.
Theoretically, radiocarbon techniques have the ability to date samples to around 75,000 years, but the working threshold of reliable dating is around 50,000 years.
Samples significantly older than this have very little or even no measurable C left.
RATE researcher John Baumgardner has dealt specifically with radiocarbon dating.
The RATE research in the area of radiocarbon has focused on the "blank" sample date.
