The geologic system is a conceptual arrangement of rock formations around the world meshed together into a single, unbroken record of Earth's past. It is also known as the geologic column or geologic timescale.
Development of the system was begun in the late 18th century, and the original divisions were Primary, Secondary, Tertiary, and Quaternary. Later, dates were assigned to the divisions according to uniformitarian beliefs about the age of the Earth, and the sections were further divided and subdivided. The system is now divided into eons, eras, periods, and series or epochs.
The naming of the eras, in particular, now reflects evolutionary beliefs (Palaeozoic / Mesozoic / Cainozoic), but the period names (Ordovician, Silurian, Cambrian, Cretaceous, etc.) still generally do not. Thus, the naming of the geologic systems is not tied to the assigned ages and assignment of an ore body to a particular geologic system does not necessarily define its absolute age.
Some young Earth creationary geologists use the nomenclature of the system whilst not accepting the uniformitarian dates attached to the system which places the age of the Earth as being billions of years old. Other young Earth creationists assert that geological column does not exist and cite secular scientists who state the argumentation advocating the geological column involves circular reasoning.   Young Earth creationist scientists use a geological system that more heavily relies on catastrophism and reject the uniformitarian assumptions behind the dates derived by secular geologists, and thus reject these dates. In addition, Young Earth creationist scientists point out that catastrophism is increasingly being accepted in the field of geology.  These scientists believe that the Earth is young and has multiple lines of evidence from the field of geology showing that the Earth is young.

Did millions of years fly by with no discernible effect? A possible though controversial inference is that our geological clocks and stratigraphic concepts need working on." William R. Corliss, Unknown Earth (Glen Arm, Maryland: The Sourcebook Project, 1980), p. 219.||”|
