" 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,"
The word "generations" implies that were more than one preceding set "of the heavens and of the earth", which ties in to the notion that the kabbalistic Qlippoth are the "shells" or remnants of earlier creations of existence - which I first came across in +Kenneth Hite's GURPS Cabal. In Urbis, the Qlippoth exist as the abode of demons, which broke into the world after a massive magical accident in the Eternal Storm region. Back when I wrote this, I was working on expanding the cosmology of D&D 3E/4E - but Pathfinder actually has the Qlippoth as distinct entities, as the original inhabitants of the Abyss who were later displaced by demons. So let's say the Qlippothic shells - remnants of earlier universes - have broken through into our universe at the Eternal Storm (as well as other, lesser and frequantly temporary gateways elsewhere). What mortals perceive as the "Abyss", the abode of demons, is actually little more than a scab - an infested wound in the world that represents a boundary between the physical plane and the deeper, alien realms of the Qlippoth. Demons are the souls of mortals and other creatures which got stuck in that wound. They present a terrible danger to all mortals, yet by their very existence they also keep the Qlippoth at bay. Whether this wound can ever heal remains uncertain.
" And every plant of the field before it was in the earth, and every herb of the field before it grew: for the LORD God had not caused it to rain upon the earth, and there was not a man to till the ground.
 But there went up a mist from the earth, and watered the whole face of the ground.
 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."
OK, first of all: Didn't God already create man (well, "male and female") back in Genesis 1:27? What happened to them, so that he would have to start anew? Where they just earlier models like the Qlippoth? And if so, are they still around in some form?
Urbis has a more "naturalistic" approach to the evolution of the world than the Bible, of course - so let's assume some kind of earlier humanoid species which may or may not have passed on their genes to what became modern-day humans, similar to how Neanderthals have passed on their genes to Europeans. I am tempted to use Blavatsky's Lemurians, who, being hermaphrodites, were "male and female" as described in Genesis 1:27. And (as I had forgotten), I've actually mentioned something like them in Urbis, as the inhabitants of the Lost Continent of Lamar.
But let's get back to verses 2:5-6. This sounds like the world had been actively seeded, but nothing was able to grow yet because there was no rain - until "a mist [went up] from the earth" and watered everything. Perhaps the aboleth bio-factories I mentioned earlier were actually terraforming engines that turned a desolate rock ball into a planet with vast oceans of water? This would certainly be a more favorable environment for the aboleth. Furthermore, the water wouldn't even need to be imported from off-world. A Decanter of Endless Water is rather cheap, yet can produce up to 30 gallons of water per round, or 5 gallons per second -157,680,000 gallons per year. Since there are 326,000,000,000,000,000,000 gallons of water in the Earth's oceans, that means that if you have about a million decanters it will take you about two million years to create the oceans from nothing - a long time, but the aboleth are nothing if not patient. It certainly must have been a sight to behold, with multitudes of geysers ejecting water into the dry air where it would turn into mist and finally condense out again once the atmosphere had its fill...
