If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.

Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.

The claimed “fact” that decay rates have always been constant is actually an inference based on a uniformitarian assumption.

It is true that radioisotope decay rates are stable today and are not largely affected by external conditions like change in temperature and pressure, but that does not mean that the rate has always been constant.

It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.

The dates must be inferred based on assumptions about the ratios.

Relative ages are assigned to rocks based on the idea that rock layers lower in the strata were deposited before rock layers that are higher.

The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.

Some of the common isotope pairs used are K-Ar, Rb-Sr, Pb-Pb, and U-Pb.

Carbon-14 dating is another common technique, but it can only be used on carbon-containing things that were once alive.

A fear of God and reverence for His Word is the beginning of wisdom.

Starting with the Bible and developing a model for dating events in earth history will lead us to the truth.
