The trace amounts of C14 in ancient human bones imply that these people died up to 50 thousand years ago. This assumes that the concentration of C14 in the atmosphere has remained constant at today's concentration. Such ages are incompatible with the record of Genesis which places Noah’s Flood about 4500 years ago, less than one half-life for C14. The trace amounts of C14 in coals buried by the Flood show that the atmospheric concentration of C14 at the time of the Flood was about 1% of today’s concentration. So C14 can be used to date ancient carbon using a biblical timescale. Here, the C14 calibration curve (“IntCal20”), based on tree ring chronologies, is recalibrated according to the C14 content of these ancient carbons: 1. coals buried in the Flood (2500 BC), 2. people in the Allen Ancient DNA Resource (AADR) who died in the Neolithic Decline (the Joseph famine of 1875 BC) and 3. tree rings from 1000 BC. By this recalibration, the secular timescale of 50 thousand years encompassing the late Pleistocene and the Stone Age becomes 1500 years from the Flood to 1000 BC. Using this biblical C14 timescale, the post-Babel settlement of Europe is revealed in the human fossil record of the AADR.
