Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means.

In this case, Argon-40 is a gas that easily bubbles out and escapes when it is produced in molten rock.

The periodic table shows the types of atoms that make up the world around us.

An element in the periodic table can come in different flavors called isotopes.

The half-life is the time that it takes for half the radioactive sample to change from one element into the other.

Some isotopes have short half-lives of minutes or years, but Potassium-40 has a half-life of 1.3 billion years.

If you’ve ever seen a horizontal slice of a tree trunk, you’ve seen how a tree forms a new growth ring each year.

For example, Potassium-40 is unstable and decays into Argon-40.

In this way, multiple trees can be used to build a master chronology for a forested region.

European oak trees have been used to build a 12,000-year chronology.

These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years.

As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.
