In the mean time, here's another snippet:

God created the “lights” in the heavens “for signs, and for seasons, and for days and years” (Gen 1:14 ). Through the marvels of astronomy we now understand that a year is the time required for the earth to travel once around the sun. The seasons are caused by the changing position of the earth in relation to the sun – “astronomers can tell exactly from the earth’s motion around the sun when one season ends and the next one begins.” (Worldbook Multimedia Encyclopedia.) We also now understand that a “month [is] the time of one revolution of the moon around the earth with respect to the sun” (Encyclopedia Britannica). How could Moses (the accepted author of Genesis) have known 3,500 years ago that the “lights” of the sun and moon were the actual determining factors of the year’s length, unless his words were inspired by God?
