A swimming race is a familiar situation that illustrates the simple principles involved in measuring time.
Once we understand what we actually need to do we can apply the same principles to radioactive dating, and see if the methods do what they are claimed to do.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
As far as I know, secular scientists have it all wrong with C14 dating because they don't take in account the Divine Flood, which engulfed billions of tons of trees and changed drastically the C14/C12 coefficient.
They focus on the technicalities of radioactive decay, etc.
but don’t even mention the fact that we can’t measure the concentrations of isotopes in the past.
And radioactive dating is so shrouded with mystery that many don’t even try to understand how the method works; they just believe it must be right.
But the basic concept of radioactive dating, sometimes called radiometric dating, is not difficult, especially since all of us regularly calculate how much time has passed: for example, since our birth, or since we started on a walk.
