In Genesis 1:26-28 God did not mention Christ or Satan, but man.
I do agree with some of what you said; but there is a little more to it. Creation is a whole lot more than just a single planet with "common life". In the "unorthodox Christian belief's" thread I did post about the origin of mankind a while back; so I fully understand the Fallen Angel's, and I do hope all our Christian brethren will eventually accept the truth of that (for their own sake).
As for John 18:36
36 Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
I did highlight the word now; for at that time the Kingdom of Heaven was withheld from the Children on this earth. As for Satan "tempting" Christ did not entirely go down the way it is written; and I would point out there was not a great many "kingdoms of men" in that area at that time.
It's required to understand the Ezekiel 28 and Isaiah 14 Scripture first about Lucifer in a time when God said he created him 'perfect' in his ways, and that he served God at His Altar. And then he coveted God's throne for himself, even claiming to be God.
Then we are supposed to 'think' about that when reading the Genesis 3 Scripture of that old serpent tempting Eve. And that serpent we are told in Revelation 12:9 is just another title for Satan. So that was Satan already in his role as adversary working against God, when he tempted Eve.
That means we have to keep 'thinking' about that, because Satan already being in the role as adversary in God's Garden tempting Eve, means he had already rebelled against God in the previous world and fallen at some point PRIOR to Genesis 3.
But when did Satan first rebel against God? Because you are right, Satan's name is nowhere mentioned back in the Genesis 1 chapter.
And the Ezekiel 31 chapter is really amazing about the time of Lucifer in the old world when he was exalted. But God uses the titles of Pharaoh and the Assyrian there when He is actually giving events about Lucifer before he fell, and then after he fell. Those who do not understand how God uses parable will argue against that being a parable, but mostly because they have yet to understand the idea of parable or allegory in God's Word.
Sorry, but our Heavenly Father and His Son expect us to use our mind, and think within His Word, not just read it blindly. There is more than one level of understanding written in His Word, and the level dealing with parables is one that I find many brethren struggle with, and I include a lot of educated pastors in that struggling too.
Ezek 28:12-15
12 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, "Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.
13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.
15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
KJV
The only flesh man that has been in God's Garden of Eden was the man Adam, definitely not that "king of Tyrus" which is a title from the historical flesh king of Tyre. And we definitely know also that no flesh man is a created heavenly anointed cherub that covereth, for that is about a heavenly created being, and in this case about Lucifer whom God created originally perfect in his ways to guard His throne. That's what Lucifer's original job was, to guard God's throne as a 'covering' cherub. If you've seen the movie Raiders of The Lost Ark, Lucifer was one of those covering cherub images shown on the lid of the ark of the covenant. That's what the idea of a covering cherub means.
So ask yourself, just WHEN was that, when Lucifer originally was created perfect in his ways, before he rebelled? Not in this present world that began at Genesis 1:6. But in that previous world when God first made His 'perfect' creation of Genesis 1:1, in the beginning.
Even though Genesis 1 is not mentioning Lucifer's original rebellion, it is covering that time in other ways, with other types of pointers. The "without form, and void" phrase is one of those pointers, because it does not mean the earth was created in a vacuum; in the Hebrew "without form, and void" actually means the earth became a waste and an undistinguishable ruin'. It was because of Lucifer's rebellion. God ended that old world, and then began this 2nd world earth age of today, starting at Genesis 1:6 thru 9.
