In the day

2:4 These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens,

Another verse ending in a comma.  Sigh.

This is another introductory verse; it could easily be 1:1, but here it is at 2:4.  There are four possibilities that I see.  One: we are going completely nonlinear, circling back to tell the same story again, perhaps to fill in missing details.  Two: we are telling a different story, although a similar one, maybe like Rashomon.  Three: someone simply shuffled all the verses around randomly.  Four: this isn't introductory, but is yet another summarizing of what went before.

Three would likely lead to an even less coherent story than we've had.  Four will quickly be shown to be wrong.  So only the first two options are contenders.  Similarities between the stories will point toward the first, which I'll call Repetition Interpretation; differences and inconsistencies will point toward the second, which I'll call the Rashomon Interpretation.

These chapters are wildly inconsistent about whether it's "heaven" or "heavens".

This is the first "Lord God".  And it's "LORD", but I'm assigning no significance to the capitalization.

It's not really clear what "generations" means.

It's interesting that it says "in the day" to refer to when God created heaven and earth.  In the previous chapter, heaven was created on the second day, and earth on the third.  So that would be two days; and in the previous chapter counting the days seemed very important.  But this reads more like "back in the day", just some vague time long ago.

By the way, when I say "the first chapter", I mean verses 1:1 through 2:3; it seems obvious that what are technically the first three verses of the second chapter are actually the last three verses of the first.

The use of "Lord" and the lack of interest in counting days already suggests that the Rashomon Interpretation is the right one.  These points are distinctly different from the previous story, and we have barely started telling the second one.  We're telling the creation story again, but this time it's a different creation story, even told by a different author, who uses different words and has different interests.

But that's just a suggestion.  More conclusive evidence will have to wait.
