First I feel it should be without a doubt obvious that revelations is littered with metaphors and poetic images. Such as the woman could not have been really given the wings of a angel, and some baby was not literally carried off into heaven.
The story is definitely about Jesus. That was the title given to Jesus, the male son King who would rule all nations with a iron rod. The days are just a couple of years. All of these events did not happen prior to creation but after creation. The metaphors here line up perfectly with Christ’s story as a child and bleeds into how he overcame the devil.
Mary gave birth to a male son who would rule all nations with a iron rod.
The woman gave birth to a male who would rule all nations with a iron rod.
The dragon tried to kill the child.
Herod tried to kill the newborn king, Jesus.
Mary, Jospeh, and Jesus fled Herod and bounced around for a while ending up in Nazarene ( place of the sticks and was safe from Herod.
The woman was given wings and the son called up to heaven and escaped the dragon into the wilderness.
In the new testament we see a high amount of demonic activity. In the old testament every time we see it we see it being used by God it was sent out by him. In the New Testament, it shows they were doing this on their own. Their time was short. They were full of wrath for being defeated.
Ultimately Jesus himself then defeated Satan and overcame death.
There was no boy back in the start who had that title, went to war with the devil, and then somehow stayed alive until they overcame the devil. It does not match up what the women being the body of believers from the Old Testament through the new.
If the argument that you’re making is that satan had already fallen sometime between genesis 1v1 and genesis 1v# it does not line up with any story relative to humanity like revelation 12 did. I’m just pointing out that it’s a weak argument to say Satan feel between verses 1 and the next verse or so as a systematic proof that there must have been time between the two.
