Carbon dating com
An animal that ingested plants with relatively low C-14 proportions would be dated older than their true age." Dating laboratories do not make any allowance for the change in atmospheric levels that would have occurred as a result of Noah's Flood.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.This problem is especially severe in shellfish or anything that eats shellfish; it is not unusual for freshly-killed seals to be dated as several thousand years old....various plants have differing abilities to exclude significant proportions of the C-14 in their intake. The varying rates at which C-14 is excluded in plants also means that the apparent age of a living animal may be affected by an animal's diet.Claims have been made of the method being calibrated back to 10,000 years using dendrochronology, C ratios the same as the atmosphere.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.That is, samples with dates known from historical records can be used to check the accuracy of the method.
Some also argue that carbon dating should only be used on samples that fall within the range over which it can measure.An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.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...strongly correlated in time, not only with each other, but also with the distance between the Earth and the Sun." It is likely that similar discrepancies and fluctuations occur with other nuclear decay rates, such as that of Many people believe that carbon dating has proved that the Earth is millions or billions of years old, much older than the biblically derived date of around 6,000 years.
