Jamieson, Fausset and Brown on Genesis 2:4

4. These are the generations of the heavens and of the earth--the history or account of their production. Whence did Moses obtain this account so different from the puerile and absurd fictions of the heathen? Not from any human source, for man was not in existence to witness it; not from the light of nature or reason, for though they proclaim the eternal power and Godhead by the things which are made, they cannot tell how they were made. None but the Creator Himself could give this information, and therefore it is through faith we understand that the worlds were framed by the word of God (He 11:3).
