Rev.12:9 is not referring to Satan in the garden, but is a future event, where at the sounding of the 7th trumpet Satan his angels will be cast out of heaven to the earth, which is also the 3rd woe.
"Therefore rejoice, you heavens and you who dwell in them!
But woe to the earth and the sea, because the devil has gone down to you!
He is filled with fury, because he knows that his time is short.”
Every seal, trumpet and bowl judgment has a resulting plague. The 7th Trumpet is no different. It starts off with a pre-celebration, then chapter 12 reveals the woman as Israel, the dragon and the stars which represent Satan and his angels and the Male Child, which is not Jesus. The results of the sounding of the 7th trumpet is Satan and his angels being cast out of heaven to the earth.
As further proof that the war in heaven is future, In Rev.19 Jesus told John to write "what you have seen, what is now and what will take place later." The what must take place later begins at Revelation 4:1 where the Lord says, "come up here and I will show you what must take place after this, i.e. after the what is now, which we are currently living in. Therefore, since the war in heaven takes place within the "what must take place later" portion of what John was told to write, then it is still a future event, which will take place at the sounding of the 7th trumpet.

You post the Scripture that says :[Rev 12:9 KJV] And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
And then you say the Scripture does not say what it says - wow
Scripture cannot lie - that 'old serpent' is the serpent from the Garden which is Satan.
Every word of God is flawless;
He is a shield to those who take refuge in Him.
Do not add to His words,
lest He rebuke you and prove you a liar. Proverbs 30
