Nephite astronomers also observed the planets, at least the major ones. In a theological argument, Alma, (Alma 30:44) spoke of "the earth, and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator." The Maya observed and recorded the movements of planets, especially Venus, as well as Mars, Jupiter, Saturn, and Mercury.
