admitted on national television he believes that the designer is God. Phillip E. Johnson, considered the father of the ID movement has stated the goal of the intelligent design movement: The Discovery Institute's leaked Wedge document sets out the movement's governing goals, including: Claimed actions Opinion as to the amount of creation the intelligent designer has done varies within the ID movement. Michael Behe's concept of irreducible complexity has natural selection accounting for most of evolution but the intelligent designer contributing the design of some proteins. Others in the ID movement however contest concepts such as common descent, particularly of humans and other apes. Though most in the ID movement seem to be Old Earth Creationists, a few are Young Earth Creationists who believe in ex-nihilo. The amount of creation that the intelligent designer did has also been criticised by Young Earth Creationists as not being specific enough, and particularly contradicting their beliefs of Biblical inerrancy and a young earth. Some intelligent design proponents say the intelligent designer fine-tuned the universe's physical constants in such a way that life is the result of the universe's physical constants being related to one another in a fashion that permits life to exist. The fine-tuned universe argument is a central premise or presented as a given in many of the published works of prominent intelligent design proponents, such as William A. Dembski and Michael Behe. Criticism Intelligent design has been presented by its proponents as a "big tent" strategy into which several accounts of creation can fit. Were a "scientific" version of intelligent design approved for inclusion in public school science curricula, then a path would be opened for discussion of alternatives to not only natural selection but naturalism as well, and eventually religious accounts on the origin of life. The vast majority of scientists reject the concept of intelligent design and an intelligent designer. Instead, the most widely accepted explanation is that physical processes such as natural selection can account for the complexity of life and other phenomena and features of the universe. Attempts to insert theories of intelligent design into public school science curricula fits in with the intelligent design movement's social aims, via the overturning of Western secularism as detailed in the Wedge strategy. The concept of the intelligent designer has been criticised as a God-of-the-gaps argument. Introducing the hypothesis of an intelligent designer introduces the unsolved problem of accounting
