ost people think carbon dating can be used to establish the age of anything old.
They believe every artifact dug up or discovered by archeologists, anthropologists, geologists, or other scientists can have its age accurately determined, within a narrow range, by carbon dating. Let’s look at carbon-14 dating to discover just how accurate and reliable it really is. First, it is based on the ratio of two elements—carbon 12 (C-12) to carbon 14 (C-14)—found in a sample of the object being dated.
We are told that of all the radiometric dates that are measured, only a few percent are anomalous.
This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.
