Radiometric dating def
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.
Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds (for example, Arndts and Overn 1981; Gill 1996) but such attempts invariably have fatal flaws (see Dalrymple 1984; York and Dalrymple 2000).
Since the rate at which certain elements decay and turn into different elements is understood, scientists are able to calculate the age of substances.It will probably fail, but what would a reasonable person conclude from that? All they indicate is that the methods are not infallible.Those of us who have developed and used dating techniques to solve scientific problems are well aware that the systems are not perfect; we ourselves have provided numerous examples of instances in which the techniques fail.Not only that, they have to show the flaws in those dating studies that provide independent corroborative evidence that radiometric methods work.This is a tall order and the creationists have made no progress so far.
