Potassium lead dating
Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.
There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms.
All our calculations could be correct (observational science), but the result could be wrong.
This is because we failed to take into account some critical assumptions.
Determining how the environment might have affected a rock also falls under historical science. Since radioisotope dating uses both types of science, we can’t directly measure the age of something.
We can use scientific techniques in the present, combined with assumptions about historical events, to estimate the age.
Scientists use observational science to measure the amount of a daughter element within a rock sample and to determine the present observable decay rate of the parent element.
Dating methods must also rely on another kind of science called historical science. Determining the conditions present when a rock first formed can only be studied through historical science.
The straightforward reading of Scripture reveals that the days of creation () were literal days and that the earth is just thousands of years old and not billions.Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.
