I don't have the time or inclination to read the short book that is the O.P. and I seriously doubt that many have done so.
But I think I have the general idea and I'll take a crack at it or at least some of it.
The first words of Genesis start out with "In the beginning". This phrase is in "construct state" and has a "Beth" prefixed preposition to it. The construct state declares that the state of one noun is dependent upon the action of another. In this case the state of heaven and earth are dependent upon the action of God. (Yeah, I know that's an "uh duh" type of observation.) Now as for the Beth prefixed preposition, it indicates the location or instrumentality of the action. So in other words, the action of what happened "in the beginning" began with God. (Yeah, I know; another "no brainer".) This is important to understand though, because what it is really saying is that all subsequent happenings (including the presence of evil) did not exist before the beginning ............................it appeared to me that evil was already present from the point that God began the creation process. I'd thought that it may have even predated creation itself ................................ From a little closer look at this word / phrase "in the beginning" though it seems that from the very commencement of any action of God - evil appeared.
It seems to me that you are assuming that the creation of the "heavens" include the heaven of spirit beings, as it were. I don't think it is necessary to read that into the passage in Genesis. He doesn't say that He created all of the 3 heavens when He created the earth. He does speak of 2 of the heavens - but not the 3rd, where He supposedly has His throne and where angels live.
"To every action there is an equal and opposite reaction."
That's a law of physics and applies to this “physical” universe. I doubt very much that it is a law which touches on the origin of evil which is not a physical concept but a philosophical one. The manifestation of evil was always possible from the 1st that beings were created and given free will.
He had to come up with a plan to adequately compensate for the opposite that would come as a result of His action.
I can't buy into your idea that "physics" (which concern the "physical universe") have any bearing on the non physical origin of evil.
Is Satan a fallen angel? I know churches teach that; I haven't found enough in Scriptures to be convinced that is actually true though. Reason would have it that if this evil predated the creation it's-self than the origins of evil could not be of some fallen angel God had made. Since nothing God would create was even in existence yet.
Evil did not predate creation. It apparently predated the creation of
this universe. But it did not predate all of creation since that would make evil an attribute of God and we know that cannot be.
And I think you agree that evil did not predate creation.
Good - then we are OK on that - if you mean before the creation of the physical universe.
But if you mean before any creation at all - I will disagree with you on that.
Yet do you acknowledge that the knowledge of good and evil had to exist prior to creation.
Absolutely. God is omniscient.
Which brings us to what I "think" is going on here.
The "Word of God" (the Son of the Father) has always from eternity reflected the glory of the His Father including all of His attributes. It has always been the Father's great pleasure to shower all that He is and all that He knows on His Son.
It has always been the great pleasure of the Son to return any glory He receives from the Father to the Father from whence comes all things.
Scriptures are available. But I'll bet that everyone here knows what they are or can find them if they try.
While the Holy Spirit is a bit more mysterious - although He is also a "person" - I believe He is the "by product" of this mutual "love" which encompasses the entire nature of God.
The creation was spoken into being to display God and "magnify" (His word) His glory.
Speaking of the Son - the scriptures say that "all things were created by Him, for Him, and in Him all things exist. That includes all things in the spirit world and in this physical universe.
IMO - God wishes to include every aspect of Who He is in this display of Himself.
One of those attributes is His inherent "knowledge of good and evil". That is - not evil itself but the "knowledge" of evil as well as good. Evil - is any rebellion against God's perfect will.
It is my opinion that, through the rebellion of Satan in heaven and mankind on earth, God is displaying "the knowledge of good and evil" in this age (at least in representative form) so that He can show in the ages to come what it is and what comes from rebellion against God's will. I believe He will wrap the “mechanism” for this display up when He moves on to "ages to come" - without having to repeat it again and again on the new earth or in any future worlds, whatever they may consist of.
IMO - God (being omniscient) knew full well the consequences of creating Satan and the rest of the angels as well as mankind with the ability to make "free will" choices.
What we see playing out in Heaven and earth - through the actions of the Son, in whom we (and everything else) live and move and have our "being" is exactly what He has done for eternity - namely receive what the Father gives to Him and return it to the Father give glory to the Father.
God is sovereign in all that He does and will accomplish all that He sets out to accomplish - or, more precisely, what He sends His Son forth to do.
"My Word be which goes forth from My mouth; It will not return to Me empty, Without accomplishing what I desire, And without succeeding in the matter for which I sent It." Isaiah 55:11
Now if we don’t like what He is doing - we, as believers, can bow our necks or receive it with humbleness as His servants.
I for one am happy to play a small part in His overall plan – even if I can’t understand it all (or even like it much).
This is particularly so because, in His grace, He has promised to “reward me” for that part I played (as painful as it was in this life) with unspeakable glory in the ages to come and all eternity.
That’s not a bad deal in the end – at least for the Son and for the elect of God, which are His bride and part of His "body".
