Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.

A full discussion of the topic must therefore include the current scientific challenge to the OE concept.

Radioactive parent (P) atoms decay to stable daughter (D) atoms e.g.

the carbon isotope C-14 decays to nitrogen-14 and the uranium isotope U-235 decays to the lead isotope Pb-207.

The time required for half the original number of parent atoms to decay is called the half life.

Some half-lives are listed below: It follows that uranium-lead, potassium-argon (K-Ar), and Rubidium-Strontium (Rb-Sr) decay can be used for very long time periods, whilst radiocarbon dating can only be used up to about 70,000 years. This uses a simple exponential decay formula linking the original number, Po, of parent atoms in rocks and minerals to the P atoms now present, thereby enabling an estimate of geological age.

One problem with earth dating is that the original earth surface is assumed to have eroded long ago.

But assuming the earth was formed at the time of the rest of our solar system, then recovered moon rock and meteorites can also be used to estimate the age of the earth.

These techniques utilize the physical parameters of the earth, such as ice cores, annual lake sediments, and astronomical cycles.The crucial point here is: if YE theory can be established scientifically, then macroevolutionary theory falls!
