Creation science or scientific creationism is a pseudoscientific form of Young Earth creationism which claims to offer scientific arguments for certain literalist and inerrantist interpretations of the Bible. It is often presented without overt faith-based language, but instead relies on reinterpreting scientific results to argue that various myths in the Book of Genesis and other select biblical passages are scientifically valid. The most commonly advanced ideas of creation science include special creation based on the Genesis creation narrative and flood geology based on the Genesis flood narrative. Creationists also claim they can disprove or reexplain a variety of scientific facts, theories and paradigms of geology, cosmology, biological evolution, archaeology, history, and linguistics using creation science. Creation science was foundational to intelligent design.

The overwhelming consensus of the scientific community is that creation science fails to qualify as scientific because it lacks empirical support, supplies no testable hypotheses, and resolves to describe natural history in terms of scientifically untestable supernatural causes. Courts, most often in the United States where the question has been asked in the context of teaching the subject in public schools, have consistently ruled since the 1980s that creation science is a religious view rather than a scientific one. Historians, philosophers of science and skeptics have described creation science as a pseudoscientific attempt to map the Bible into scientific facts. Professional biologists have criticized creation science for being unscholarly, and even as a dishonest and misguided sham, with extremely harmful educational consequences.
