Tree ring dating method
In addition to allowing more certain proof of a tree's age, it allows dendrochronologists to link together a part of the life of one tree to part of the life of another tree and make an effective "chain" of tree lives.
Young Earth creationists often doubt other forms of dating, such as radiometric dating, that invalidate their worldview of a 6,000-year-old Earth, often because those dating methods are harder to understand, more prone to potential error, and science-y.
The increment borer removes a small cylinder or core of wood from the tree trunk.
By counting the thin bands (annual rings) on the wood cylinder, the approximate age of the tree can be determined.
Example: analyzing ring widths of trees to determine how much rainfall fell per year long before weather records were kept.

Many trees in temperate zones make one growth ring each year, with the newest adjacent to the bark.
