Thanks, I know you probably have a lot of comments to keep up with so I didn't want to be pushy, but I appreciate your thoughtful response!
I don't think this quote actually supports your position all that well, if we examine it. You would have to insist that by "all things in (the world)" it means God created it all before Gen 2:1, when in fact there are many easy examples of things in the world that ancient Hebrews would have known to be of more recent origin: plants, animals, humans and their souls, tools, houses, cities, etc.
The way it is clearest to think of it for me is that there is a progression that can be observed in the first six day of what kinds of things are being created. First are the large-scale but not as complex/close to us things (sea, sky, land) and then more remote/dissimilar (astronomical bodies) going towards things closer to us: fish, birds, land animals. It's like zeroing in from a wide focus to a very specific one, only there's more detail and intricacy the more you narrow in on humans. And God's saying He didn't continue to create even more advanced humans, or other beings more God-like. If He did not call creation finished, we would have to wonder what the next level of creating He would be doing was, as opposed to just more of the same kinds of things Genesis has already described him as creating.
I like the idea of the noosphere, that the realm of ideas is where we see the most continuing change and growth; but that is change and growth driven by humans, with input from God (and as you say, God gets final judgement) but God is not the sole driver anymore: He deliberately relinquished complete control over what people would say or do.
A lot of very interesting concepts to wonder about, to be sure! Sorry it took me a little longer than I hoped to get them written out in a hopefully sensible sequence!
Brings to mind this one: "As it was in the beginning, is now and ever shall be, world without end!"
