Only conscious creation that is capable of choosing is capable of sin - humans, for example. Or any other beings with similar agency.
So as I said, creation is incapable of sinning. Neither God nor creation are capable of choosing, so in that sense at least, we agree, they're equal. They're incapable of sinning.
Some creation is conscious, like humans, animals, higher dimension beings (angels). Some is not (like stones, wind or stars). Things do not have mechanism for thought processing and choosing.
I'll ask again, how do you know that creation isn't conscious?
This time I'll answer it for you: You don't.
God is not capable of sinning because His perfections make it impossible for God to "miss".
Ditto for creation, it is what it is, and in no sense could it be 'better' than it is. (If it could, your God would've created it so... is this not true?) Hence, whether it is perfect of its own accord, or it was created so by God, creation is as perfect as it could possibly be.
Creating the creation. Preserving the creation. Ruling the creation for the best possible outcomes.
Ah, but now we get to the crux of the dilemma, how do you know that the creation was actually 'created'? Were you there? What evidence do you have? Perhaps it's not a creation at all. Since it bears all the hallmarks, and attributes of your God, perhaps the 'creation' and the 'creator' are one and the same thing, and 'creation' is merely your limited human perspective of the "Creator". It's God the Creator, seen through human eyes.
Creation exists in God, its has its laws and boundaries, limits. God, on the other hand, is "apeiron".
Out of curiosity again, if creation exists in God, and presuming that God exists in creation, then what would you say differentiates the two? Isn't the creation simply a manifestation of the creator? The absolute best of which its capable? If so, then the creation is no better or worse than its creator. At worst, it's its equal, and at best, it's the Creator Himself.
I could go on. I love philosophy, but alas we're way off topic. Perhaps another place and another time.
