A favorite tactic of creationists is to label any part of science that they do not like as a "theory". Then they imply that when it comes to "theories" you can take them or leave them. To those familiar with the methods of science this is plain nonsense. There are well-established theories that no working scientist can do without--quantum theory or relativity theory in physics, for example. There are also lunatic-fringe theories that create nothing but confusion, for example, the most extreme form of the Gaia hypothesis claims that the whole world of life on the Earth is a single living, caring organism. What is the standing of theories on the origins of life?
