The National Park Service website documentation and Wikipedia article regarding California's Channel Islands is in error.
The people supposedly that were on the Channel Islands, whose bones have been found, are erroneously reported to be 13,000 years old.
This is a case where the Great Flood has left us a clue, and modern fuck-ass man has given God the finger.
Those bones cannot be more than 6,000 years old at the time of the beginning of the 7th Millenium, January 1, 2000 A.D.
Best solution :
The machine should be calibrated to be Biblically accurate and in accord with this using the best estimation of when the time of the Great Flood occurred, and then compare the accuracy of the machine with something that is not as old.
Worst solution :
attempt to prove me wrong
