The '''geologic system''' is a conceptual arrangement of rock formations around the world meshed together into a single, unbroken record of earthEarth's past.<ref>Wile, Dr. Jay L. ''Exploring Creation With General Science''. Anderson: Apologia Educational Ministries, Inc. 2000</ref> It is also known as the '''geologic column''' or '''geologic timescale'''. The geologic system supports a [[Young Earth]], and multiple distortions are used by [[atheist]]ic scientists to obscure and deny that.
== Development ==
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 [[uniformitarianism (science)|uniformitarian]] beliefs about the age of the Earth, and the sections were further divided and subdivided.
The system is now divided into [[eon (geology)|eons]], [[era (geology)|eras]], [[period (geology)|periods]], and [[epoch (geology)|series or epochs]].
Dr. [[Jonathan Sarfati]] explains the relationship between sections of the geologic system and [[Theory of evolution|evolutionary]] belief:
== Problems ==
Some [[Young earth Earth creationism|young earth 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 Earth as being billions of years old.<ref>"Creationists use the same naming system, although do not accept the uniformitarian belief that the geologic column represents eons of time", Batten, Don, quoted in Sarfati, Jonathan, [http://www.creationontheweb.com/content/view/2280 More nonsense from Professor Plimer]</ref><ref>Morris, 1973; Geologic Time Scale - The Misconceptions</ref>Other young earth Earth creationists assert that geological column does not exist and cite secular scientists who state the argumentation advocating the geological column involves circular reasoning. <ref>Woodmorappe, 1999</ref> <ref>Northside Church of Christ</ref>Young earth Earth creationist scientists use a geological system that more heavily relies on [[Catastrophism|catastrophism]] and reject the uniformitarian assumptions behind the dates derived by secular geologists, and thus reject these dates. In addition, [[Young earth Earth creationist]] scientists point out that [[catastrophism]] is increasingly being accepted in the field of geology. <ref>Roth, 1985; Morris, 1976</ref>These scientists believe that the earth Earth is young and has multiple lines of evidence from the field of geology showing that the earth Earth is young. <ref>http://www.answersingenesis.org/home/area/faq/geology.asp</ref> <ref>http://www.creationism.org/topbar/geology.htm</ref> <ref>http://www.grisda.org/georpts/gr11.htm</ref> <ref>http://www.nwcreation.net/geologylinks.html</ref> <ref>http://globalflood.org/</ref>

[[William R. Corliss]] wrote the following about [[paraconformity|paraconformities]]:
{{cquote|"Potentially more important to geological thinking are those [[unconformity|unconformities]] that signal large chunks of geological history are missing, even though the strata on either side of the unconformity are perfectly parallel and show no evidence of erosion. 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.<ref>http://www.cs.unc.edu/~plaisted/ce/flood.html</ref>}}Trees have also been found going through multiple strata.

{{cquote|Paraconformities challenge the geologic timescale. The lack of evidence of time at the surface of the underlying layers of a paraconformity, especially the lack of erosion, suggest that the long ages never occurred.<ref>http://www.grisda.org/georpts/36.pdf</ref>}}
Young earth creationist Earth creationists assert that paraconformities pose a serious challenge to the old earth Earth uniformitarian geology [[paradigm]].<ref>http://www.grisda.org/georpts/36.pdf</ref><ref>http://www.grisda.org/2003-FSC-open/Roth-RecentCreation.htm</ref><ref>http://www.seeking-god.co.uk/id188.htm</ref>
