Two Creation Accounts?

Here is a good summary of the reasons to reject the Documentary Hypothesis concerning Genesis 1-2.

Another point concerning the two names for God found in Gen. 1 and 2, that the author of the article did not mention, is that since Gen. 1 describes a broad view of creation, the generic name for God ("Elohim") is used. Whereas in the more intimate account of creation in Gen. 2 focusing on man, the covenant name for God ("Yahweh") is used, which is entirely fitting.
