Christian perspective on radiometric dating
Astronomy and Geology, working on scientific data built up over the last two centuries or so, assumes the Earth to be very ancient, more in keeping with the eastern than the western (Graeco-Judeo-Christian) perspectives.
However, whereas the Eastern perspective is (like the Greek) cyclic, the Western scientific understanding is strictly linear and evolutionary.
Of course C-14 would never be of any use for dating dinosaur bearing deposits, unless you want everything to date to around 40,000 years!
Ihis has made it useful for measuring prehistory and events occurrring within the past 35 to 50 thousand years.The Christian Creationists have criticised it on the grounds that it is innacurate.But these innacuracies are the result of variation in the level of Carbon 14 in the atmosphere, and when this is worked out (through calibration with tree rings of the bristlecone pine, the oldest living organism) precise dates can be had.Even in the case of very long half-lives, modern scientific instruments are now accurate enough to give very fine readings.We usually hear of Carbon 14 dating, which is very important in archaeology.
