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 materials 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.

The First Amendment (Amendment I) to the United States Constitution is part of the Bill of Rights. The amendment prohibits the making of any law respecting an establishment of religion, impeding the free exercise of religion, abridging the freedom of speech, infringing on the freedom of the press, interfering with the right to peaceably assemble or prohibiting the petitioning for a governmental redress of grievances.
Originally, the First Amendment applied only to laws enacted by the Congress. However, starting with Gitlow v. New York, the Supreme Court has applied the First Amendment to each state. This was done through the Due Process Clause of the Fourteenth Amendment. The Court has also recognized a series of exceptions to provisions protecting the freedom of speech.
