(The item being tested must be organic based, and must be dead - tests on live mollusks showed an age of 2000 years).

If a fossil is completely replaced (permineralized), then it would be useless in a similar test - because it no longer is organic.

These unstable atoms tend to "decay" into stable ones; they do this by emmitting a particle or particles. The time it takes for half of a given amount of a radioactive element to decay into a stable one is what is known as the "half-life".

By matching the proportion of original unstable isotope to stable decay product, and knowing the half-life of that element, one can thus deduce the age of the rock , as shown in the follwoing diagram.

The Greeks had the "great year" of 24,500 years, based on the precession of the equinoxes.

The time-scale of the fundamentalist or Creationist Judeo-Christian is based on a word-for-word reading of the first book of the Bible, and assumes a total age of the earth and the cosmos of a mere 5 or 6,000 (some Creationists allow 10,000) years.

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.

Some Thermoluminescense dates that are in the order of 50,000 years /- 25,000 years, which with a two standard deviation limit puts it anywhere between yesterday and 100,000 years ago.During the 19th century, and even well into the twentieth, geological chronology was very crude.Dates were estimated according to the supposed rate of deposition of rocks, and figures of several hundred million years were bandied out; usually arrived at through inspired guesswork rather than anything else.These elements have much longer half-lives than Carbon, and in some cases can be cross-referenced if more than one of these elements is present in avolcanic tuft.

There are other methods for dating fossils, such as themolumenescence.Different world-views have different time-scales as regards the history of the Earth and the universe.
