The '''Pre-Cambrian''' or Cryptozoic is the period of the geologic timescale from the formation of Earth (around 450 billion years before the present era) to the evolution of abundant macroscopic hard-shelled fossils, which marked the beginning of the Cambrian, some 542 million years ago. The majority of the evidence existing about the Precambrian has largely been discovered in the past four or five decades, but much has been destroyed or hidden by long-term geological processes such as erosion and plate tectonics.

Creationist scientists do not believe the [[Theory of evolution|evolutionary]] geological timescale is legitimate. [http://www.trueorigin.org/geocolumn.asp][http://www.icr.org/index.php?module=articles&action=view&ID=54]

[[Young earth creationist]] scientists believe that the [[Theory of evolution|evolutionary]] [[Geology|geological]] timescale is in error. <ref>http://www.trueorigin.org/geocolumn.asp</ref><ref>http://www.icr.org/index.php?module=articles&action=view&ID=54</ref><ref>http://www.allaboutcreation.org/geologic-time-scale.htm</ref>  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. <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>  Also, young earth creationist scientists assert that there is an abundance of scientific arguments in addition to geology showing the earth and universe are both approximately 6,000 years in age.<ref>http://www.answersingenesis.org/home/area/faq/young.asp</ref><ref>http://www.answersingenesis.org/home/area/faq/astronomy.asp</ref><ref>http://www.icr.org/article/1842/</ref>  In addition, young earth creationist scientists have a number of arguments against the position of an extremely old age for the earth and the universe.<ref>http://www.answersingenesis.org/home/area/faq/dating.asp</ref><ref>http://www.answersingenesis.org/home/area/faq/astronomy.asp</ref><ref>http://www.apologeticspress.org/modules.php?name=Read&cat=1&itemid=22</ref>
