'''Fossils''' are preserved remains of once-living organisms.<ref>Wile, Dr. Jay L. ''Exploring Creation With Biology''. Apologia Educational Ministries, Inc. 1998</ref> They are usually formed when mineral-rich water makes its way into the deceased being's body. The minerals within the water aggregate within the spaces within the body and solidify. Once the organism's tissues have dissolved away, all that is left behind is a rock mold of the creature's shape. Sometimes, however, the mineralization process occurs quickly enough that soft tissue is preserved perfectly, lasting for millions of years.

The oldest fossil ever discovered that scientists agree on is that of prokaryotes of approximately 2.5 billion years old found in the Gunflint Chert of Western Ontario.  There are some debated fossils from the Apex Chert in Australia that are about 3.4 billion years old. These fossils already show well-developed organisms, suggesting that life had already existed for a while.

The oldest eukaryotes are red alga fossils that are dated to about 1.2 billion years.
