The
Genesis creation narrative is the
creation myth of both
Judaism and
Christianity. It is made up of two parts, roughly equivalent to the first two chapters of the
Book of Genesis.
In the first part (
Genesis 1:1–2:3)
Elohim, the Hebrew generic word for
God, creates the heaven and the earth in six days, starting with darkness and light on the first day, and ending with the creation of mankind on the sixth day. God then rests on, blesses and sanctifies the
seventh day. In the second part (
Genesis 2:4–2:24) God, now referred to by the personal name
Yahweh, creates the
first man from dust and breathes life into him. God then places him in the
Garden of Eden and creates the
first woman from his side as a companion.
A common hypothesis among
modern scholars is that the first major comprehensive draft of the
Pentateuch (the series of five books which begins with Genesis and ends with
Deuteronomy) was composed in the late 7th or the 6th century BC (the
Jahwist source) and that this was later expanded by other authors (the
Priestly source) into a work very like the one we have today.
[7]
The two sources can be identified in the creation narrative:
Genesis 1:1–2:3 is Priestly and
Genesis 2:4–2:24 is Jahwistic.
[8] Borrowing themes from
Mesopotamian mythology, but adapting them to Israel's
belief in one God,
[9] the combined narrative is a critique of the Mesopotamian theology of creation: Genesis affirms monotheism and denies polytheism.
[10] Robert Alter described the combined narrative as "compelling in its archetypal character, its adaptation of myth to
monotheistic ends".................

The two stories depict two different primordial scenes.
Genesis 1 begins with pre-existent chaotic matter—darkness and a watery deep—that is about to be “tamed” by God during the six-day sequence. The spirit of God hovers over the deep, and begins the creation sequence by first making light (1:3-5) and then dividing the waters (1:6-10). Genesis 1 shows how God makes habitable what is uninhabitable.
Genesis 2 depicts a similar transition from inhabitable to habitable, but it does not describe the primordial state in the same way. Instead, we find ourselves in a
land that is not yet fully habitable. There are streams watering the earth. The presenting problem is not chaos but absence of plant life because there was neither rain nor anyone to work the land.
The setting of the scene for creation is different in these two accounts.
