God Said and it was

Judaism marks the world’s first transition on a national scale from an oral to a literate culture. Hence the unique significance it attaches to the spoken and written word. We discover this at the very beginning of the Torah. It takes the form of the radical abandonment of myth. G-d spoke and the world came into being. There is no contest, no struggle, no use of force to subdue rival powers – as there is in every myth without exception. Instead, the key verb in Genesis 1 is simply leimor, “G-d said [vayomer], Let there be . . . and there was.” Language creates worlds.

The Chief Rabbi J. Sacks

Creation is our responsibility

Wisdom on parshas Noach from the Lubavitcher Rebbe:

According to the Torah, the world was created by G-d using the Name "Elokim". The Name used in reference to Noach, however, is the ineffable name of G-d that cannot be pronounced.

Elokim, has the numerical equivalent of the Hebrew word for "nature," and represents a level of holiness that is limited. Whereas G-d's ineffable name (yud - hey - vav - hey) represents a level above all limitations.

We learn from this that the world, as it was created without man's contribution, has the potential for only a limited revelation of G-dliness. It is solely through the service of man that the higher, infinite and unlimited revelation of G-dliness is achieved.
