Old Earth creationism in the context of "Day-age creationism"

Creationism is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation, and is often pseudoscientific. In its broadest sense, creationism includes various religious views, which differ in their acceptance or rejection of modern scientific concepts, such as evolution, that describe the origin and development of natural phenomena.

The term creationism most often refers to belief in special creation: the claim that the universe and lifeforms were created as they exist today by divine action, and that the only true explanations are those which are compatible with a Christian fundamentalist literal interpretation of the creation myth found in the Bible's Genesis creation narrative. Since the 1970s, the most common form of this has been Young Earth creationism which posits special creation of the universe and lifeforms within the last 10,000 years on the basis of flood geology, and promotes pseudoscientific creation science. From the 18th century onward, Old Earth creationism accepted geological time harmonized with Genesis through gap or day-age theory, while supporting anti-evolution. Modern old-Earth creationists support progressive creationism and continue to reject evolutionary explanations. Following political controversy, creation science was reformulated as intelligent design and neo-creationism.

Young Earth creationism (YEC) is a form of creationism that holds as a central tenet that the Earth and its lifeforms were created by supernatural acts of the Abrahamic God between about 10,000 and 6,000 years ago, directly contradicting established scientific data that puts the age of Earth around 4.54 billion years. Events such as Noah’s Flood are described as explaining much of the geological and fossil record. In its most widespread version, YEC is based on a religious belief in the inerrancy of certain literal interpretations of the Book of Genesis. Its primary adherents are Christians and Jews who believe that God created the Earth in six literal days, as stated in Genesis 1. Among the biggest young Earth creationist organizations are Answers in Genesis, Institute for Creation Research, and Creation Ministries International.

This is in contrast with old Earth creationism (OEC), which holds that literal interpretations of Genesis are compatible with the scientifically determined ages of the Earth and universe, and theistic evolution, which posits that the scientific principles of evolution, the Big Bang, abiogenesis, solar nebular theory, age of the universe, and age of Earth are compatible with a metaphorical interpretation of the Genesis creation account.

Progressive creationism is the religious belief that God created new forms of life gradually over a period of hundreds of millions of years. As a form of old Earth creationism, it accepts mainstream geological and cosmological estimates for the age of the Earth, some tenets of biology such as microevolution as well as archaeology to make its case. In this view creation occurred in rapid bursts in which all "kinds" of plants and animals appear in stages lasting millions of years. The bursts are followed by periods of stasis or equilibrium to accommodate new arrivals. These bursts represent instances of God creating new types of organisms by divine intervention. As viewed from the archaeological record, progressive creationism holds that "species do not gradually appear by the steady transformation of its ancestors; [but] appear all at once and "fully formed."

The view rejects macroevolution, claiming it is biologically untenable and not supported by the fossil record, as well as rejects the concept of universal descent from a last universal common ancestor. Thus the evidence for macroevolution is claimed to be false, but microevolution is accepted as a genetic parameter designed by the Creator into the fabric of genetics to allow for environmental adaptations and survival. Generally, it is viewed by proponents as a middle ground between literal creationism and theistic evolution.

Islamic views on evolution are diverse, ranging from theistic evolution to Old Earth creationism. Some Muslims around the world believe "humans and other living things have evolved over time", yet some others believe they have "always existed in present form". Some Muslims believe that the processes of life on Earth started from one single point of species with a mixture of water and a viscous clay-like substance. Muslim thinkers have proposed and accepted elements of the theory of evolution, some holding the belief of the supremacy of God in the process. Some scholars suggested that both narratives of creation and of evolution, as understood by modern science, may be believed by modern Muslims as addressing two different kinds of truth, the revealed and the empirical. Others argue that faith and science can be integrated and complement each other.
