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.
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.However, there are many methods that can be used to determine the age of the earth or other objects.The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming?
For since the fathers fell asleep, all things continue as they were from the beginning of creation.” For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, by which the world that then existed perished, being flooded with water.
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.
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.
Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.
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.
