The creation–evolution controversy (also termed the creation vs. evolution debate or the origins debate) involves an ongoing, recurring cultural, political, and theological dispute about the origins of the Earth, of humanity, and of other life. Within the Christian world, creationism was once widely believed to be true, but since the mid-19th century evolution by natural selection has been established as an empirical scientific fact.
The debate is philosophical, not scientific: in the scientific community, evolution is accepted as fact and efforts to sustain the traditional view are almost universally regarded as pseudoscience. While the controversy has a long history, today it has retreated to be mainly over what constitutes good science education, with the politics of creationism primarily focusing on the teaching of creationism in public education. Among majority-Christian countries, the debate is most prominent in the United States, and to a lesser extent in Europe and elsewhere, and is often portrayed as part of a culture war. Parallel controversies also exist in some other religious communities, such as the more fundamentalist branches of Judaism and Islam.
Christian fundamentalists dispute the evidence of common descent of humans and other animals as demonstrated in modern paleontology, genetics, histology and cladistics and those other sub-disciplines which are based upon the conclusions of modern evolutionary biology, geology, cosmology, and other related fields. They argue for the Abrahamic accounts of creation, and, in order to attempt to gain a place alongside evolutionary biology in the science classroom, have developed a rhetorical framework of "creation science". In the landmark Kitzmiller v. Dover, the purported basis of scientific creationism was exposed as a wholly religious construct without formal scientific merit.
