People who study science are called [[scientist]]s. Most of the early scientists who started many of the scientific fields, and some of history's greatest thinkers, such as [[Galileo Galilei]] and [[Isaac Newton]], believed in [[God]], or some other higher power, and many were [[creationists]], although the ideas of [[evolutionism]] or [[Darwinism]] were not yet popular.
In addition, [[Christianity]] played a pivotal role in the development of modern science (see [[Christianity and Science]]). With further scientific advancement, the scientific approach has become increasingly [[atheism|atheistic]],<ref>http://www.atheists.org/flash.line/atheism1.htm</ref> rejecting the supernatural. Scientific fields of study observing a clear atheistic bent include [[Counterexamples to Evolution|evolution]], [[global warming]] and much of [[cosmology]] and [[geology]], which are based on a [[Counterexamples to an Old Earth|time frame]] which predates the Christian time of [[creation]]. There are hubs of real scientific research, however, in places like the Institute for Creation Research and the Heartland Institute.
Science differs from other methodologies of classifying knowledge in that a scientific theory is a description of the world which in principle is capable of being disproved; this is known as [[falsifiability]]. It is this property which distinguishes science from other possible methods of discovering knowledge.
