The seventh verse speaks of "war in heaven".
In the case of Christ and the Manchild, the prophecy can refer back to the original casting out of Satan.
There are several "casting out of Satan", each forcing him to a lower and more restricted sphere until at last he is locked in the Bottomless Pit.
Prophecy never has primary reference to something that has already happened, but to things in the future.
Satan is cast out of the heavenlies shortly after the Manchild is caught up to heaven.
