It is hard to find a fundamental difference between the individual biblical creation accounts and other creation stories.
The first creation account in Genesis (Genesis 1:1-2:4a) is quite similar to the Sumerian creation story, which is generally accepted as having been encountered by the Jews during the Babylonian Exile. It has been noted that this creation account is typical of seaside cultures.
The second creation account in Genesis is similar to older Canaanite creation stories. It has been noted that this creation account is typical of cultures in arid areas.
There are fragments of another creation account in Job, Psalms and elsewhere in the Bible, that point to an ancient belief in chaos monsters. Again, much of the ancient Near East believed that the world originated in a dramatic struggle between good and chaos gods.
The biblical creation does differ from the creation accounts of other cultures, in that two quite different and basically irreconcilable accounts have been retained more or less intact, and yet few believers would see this as irrational.
