Dating techniques for fossils

Uniformitarian geologists use so-called dating methods to determine the ages of the surrounding rocks.Certain types of rocks, especially those that form from magma (igneous), contain radioactive isotopes of different elements.If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.

Most radiometric dating techniques must make three assumptions: The major problem with the first assumption is that there is no way to prove that the decay rate was not different at some point in the past.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.The Bible gives us a much more reliable history of the earth as it was recorded by God.When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating.

If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.
