At a broad level, a Creationist is someone who believes in a god who is absolute creator of heaven and earth, out of nothing, by an act of free will. Such a deity is generally thought to be constantly involved (‘immanent’) in the creation, ready to intervene as necessary, and without whose constant concern the creation would cease or disappear. Christians, Jews, and Muslims are all Creationists in this sense. Generally they are known as ‘theists,’ distinguishing them from ‘deists,’ that is people who believe that there is a designer who might or might not have created the material on which he (or she or it) is working and who does not interfere once the designing act is finishing. The focus of this discussion is on a narrower sense of Creationism, the sense that one usually finds in popular writings (especially in America today). Here, Creationism means the taking of the Bible, particularly the early chapters of Genesis, as literally true guides to the history of the universe and to the history of life, including us humans, down here on earth (Numbers 1992).
