Atheist Bible Study 1: Genesis

[Jehanne]

There are many ways to study writings, including textual criticism and sharing one's personal thoughts on what they just read.

I disagree. If you do not know where the text comes from, who wrote it, when, the type of literature and that it is different then the rest of the book of Genesis, you can't possible just read it and think you can understand it. What you just said is how we get YEC.

Genesis was written by multiple authors:

The documentary hypothesis (DH) is one of three models used to explain the origins and composition of the first five books of the Bible,[Note 1] called collectively the Torah or Pentateuch. The other two theories are the supplementary hypothesis and the fragmentary hypothesis.[1][2]

All three agree that the Torah is not a unified work from a single author (traditionally Moses) but is made up of sources combined over many centuries by many hands. They differ on the nature of these sources and how they were combined. According to the documentary hypothesis there were four sources, each originally a separate and independent book (a "document"), joined together at various points in time by a series of editors ("redactors").[3] Fragmentary hypotheses see the Torah as a collection of small fragments, and supplementary hypotheses as a single core document supplemented by fragments taken from many sources.[4]
