"And God set them [sun, moon, and stars] in the firmament of the heaven to give light upon the earth...." (Gen. 1:17)

Notice: God SET them.... Now, inside our so-called "solar" system, we have only the sun and the moon (from the verse above). We KNOW the moon moves. Therefore, when God SET IT "in the firmament", the inescapable meaning is that He set it in motion on the track it follows. When He set THEM in the firmament it is a grammatical imperative that He set the sun and stars in motion ALSO on their tracks just like He set the moon in motion on its track.
