At the morethodoxy.com blog, Rabbi Hyim Shafner cites classic Jewish commentators on the Book of Genesis regarding how we are to understand the creation story:
The first is Rash”I (Rabbi Shlomo Isaac of Worms, France 1040CE-1105CE) who claims that the bible’s creation story is incorrect since it describes God as having separated the waters before their creation and contains various other inconsistencies. ....Nachmonides, perhaps the second most well known of the Jewish biblical commentators argues that we do need the story of the creation so that we can know it is God who made the universe, but says Nachamonides, from the story as it is described in Genesis we can discern nothing about the creation. The actual story of creation, says Nachmonides, was told only to Moses. Those few who know it do not say, and those say do not know it.
Creationism simply is not very interesting to the authoritative Jewish sources.
