Industrial revolution radiocarbon dating
For example, it is well known that carbon dating cannot be used on many types of marine life due to reservoirs of "old" carbon held in sedimentary rocks.
Radiocarbon dating uses the naturally occurring isotope Carbon-14 to approximate the age of organic materials. Often, archaeologists use graves and plant remains to date sites.
This means that radio-carbon dates cannot be used to prove that the Flood did not occur, because it assumes that it did not occur.
Scientists at Brookhaven National Laboratory and the Physikalish-Technische-Bundesandstalt in Germany have reported "unexplained periodic fluctuations in the [nuclear] decay rates of Si-32 and Ra-226...
Despite this, however, caution is still necessary in accepting dates derived from carbon dating.
Claims have been made of the method being calibrated back to 10,000 years using dendrochronology, C ratios the same as the atmosphere.
