In 1987, the Supreme Court overturned a Louisiana law that required creationism be taught alongside evolution. The court ruled that Genesis, the biblical story of creation, was a religious belief and due to the separation between state and religion, was prohibited from being taught in the public school system. What appeared to be a crushing blow to creationism only whetted the appetites of creationists. The Kansas decision is not the anomaly many people think. In Alabama, science books have the equivalent of a parental advisory sticker pasted on the cover.
Evolution is just a theory that some scientists believe.
Alabama, New Mexico and Nebraska teach that evolution is one possible explanation for the origin of the universe, as is creationism. Texas, Ohio, Washington and New Hampshire have considered but rejected such changes. The Tennessee legislature is considering a bill that would make it illegal to teach evolution. Now, to scientists, evolution is the bedrock of biology, based on fossils and genetics. The stones and bones tell them that Earth was created about 4.5 billion years ago possibly as a result of a Big Bang in the universe, life evolved about 3.9 billion years ago from one cell to multi-celled creatures and humans and other species evolved from a common ancestor.
