According to part of Genesis, the moon is a light source just like the sun, only not as bright. If this was the case, astronauts couldn't land on the moon, it would be too hot. It is also strange that it took God the day to make the sun and the moon, but the stars are portrayed as an afterthought of sorts. "He made the stars also", this is a definite sign that the Bible is inspired by man. It is clear that man could not have perceived that the stars were the same as the sun, but in most cases much larger. Naturally they thought that these specks were just thrown about. The verse should read "God created the stars and planetary objects, he also made the earth, sun, and moon". But man, in those days, would have never seen it that way.
