For what it’s worth, it seems like it is a third option, he is collapsing two closely related events into one sentence, as is common to do linguistically. Not careless at all, and perhaps even intentional.
Even if Genesis 1 and 2 are the same event, it still works with the GAE though.
@AJRoberts thanks for the kind words. I agree with just about all you wrote. Let’s say GAE pans out. What do you think the remaining hang ups are?
