Paleontology

From RationalWiki

Paleontology is the study of fossils, which are the remains of living things, some of which are mineralized, and some that have been preserved relatively intact by natural processes. Paleontologists also get useful information from studying fossil tracks or footprints, and fossil remains of feces (coprolites). In addition, the trails and burrows of creatures such as marine worms in bottom sediments of bodies of water provide valuable information.

Young earth creationists don’t like paleontology because (like most real science) it provides hard evidence that life evolved over billions of years, and makes a laughingstock of the idea that the Earth was created over the course of six days, approximately six to ten thousand years ago.
