Before:
Scholars have argued that Genesis 1 comes from the Priestly source, written around the fifth century BCE, while Genesis 2-3 is attributed to the Yahwist source and believed to have been written around the tenth century BCE. Both of these stories give completely different accounts of how the creation of the world took place. The Priestly source provides a very ordered narrative, with God removed from the world and dealing predominately with the cosmic elements of the story, whereas the Yahwist source portrays a much more earthly focused and anthropomorphic God; this directly relates to the focus of each narrative, with Genesis 1 providing less finite details on the creation of humanity while Genesis 2-3 goes into great detail.
After:
I have not made this edit yet because it will take more time to do and more research on my part to provide an apt explanation, but I am going to go into more detail about what the Yahwist and the Priestly sources are. Those of us who have taken courses on the Hebrew Bible will know these terms, but they are not accessible for everyone. It may just end up being a footnote because it is not that important to the thesis of my paper, but I acknowledge that the layman will probably not know these terms. Thoughts on footnote/paragraph?
