Dating introduction ring tree
Chronological sequence is all that is really required.
However, human beings love to see factual precision, and we want to know how old something is.
For example, modern biblical chronology dates Noah's Flood to 3520 /- 21 B.
Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
Modern radiocarbon dating uses tree-ring chronologies to produce the calibration curve.
Because the radiocarbon to stable carbon ratio in the atmosphere has fluctuated over time, there are "wiggles" in the calibration curve.
Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.
Dating is not necessary to demonstrate that evolution is a fact.
Radiocarbon dates are certainly not precise to within a year or two, but they are generally precise to within a few hundred years or better.
This means radiocarbon's precision is generally sufficient to choose between alternate chronologies which differ by a hundred years or more.
A few examples of such lies are presented at the very bottom of this page.
For each dating or chronological method there is a link in the box at right to take you to that section of this page.
This, in fact, is the most significant factor contributing to loss of precision in radiocarbon dates today.
