The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.

The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.

First, it provides no evidence whatsoever to support their claim that the earth is very young.

If the earth were only 6000–10 000 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far.

Where are the data and age calculations that result in a consistent set of ages for all rocks on earth, as well as those from the moon and the meteorites, no greater than 10 000 years? Second, it is an approach doomed to failure at the outset.

Creationists seem to think that a few examples of incorrect radiometric ages invalidate all of the results of radiometric dating, but such a conclusion is illogical.

Radiogenic, non-traditional stable & rare gas isotopes.

Le Centre de Recherches Pétrographiques et Géochimiques (CRPG), Nancy, France: The CRPG is a joint facility of the Centre National de la Recherche Scientifique and University of Lorraine comprising ~100 people (including support staff and students) working in the field of Earth and Planetary Science.

In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.Answer 2: Yes, radiometric dating is a very accurate way to date the Earth.We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes. This is an enormous branch of geochemistry called Geochronology. It is an accurate way to date specific geologic events.It hosts two national analytical facilities, the Service for the Analysis of Rocks and Minerals (Service d'Analyse des Roches et des Minéraux - SARM -) and the ion probe facility.
