"In 1996, NOVA Online asked two leading spokesmen in the evolution/creation debate to discuss the question, "How did we get here?" The participants have agreed to keep their letters to less than 500 words and have been given equal time to write them. It should be noted that neither Miller nor Johnson were involved in the production of NOVA's Odyssey of Life."
Reading this exchange of letters makes it fairly clear that Miller would prefer to discuss science and Johnson would rather not.
