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.
Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.
There is also a difference in the timescale used to explain the layers.Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it.There are three main assumptions that must be made to accept radiometric dating methods.These must be accepted on faith in uniformitarian and naturalistic frameworks.Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
The Bible gives a much different picture and explains that relying on man’s reasoning is foolishness.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.The claimed “fact” that decay rates have always been constant is actually an inference based on a uniformitarian assumption.
