You do realize your take on the sun, moon, and stars falling is the Preterist interpretation? These astronomical things are predicted in Matt. 24. The Preterists tell us Christ came in 70 AD, to have that happen they have to do something with the astronomical conflagrations that happen in conjunction with his coming.
No problemo, they take care of it just like you did. They spiritualize the astronomicals, and make the 2nd coming in Matt. 24 not to be an actual literal coming of Christ, but is poetic language for “judgment.” You are not Preterist are you?
*Falling stars – There will be celestial phenomenon, such as falling stars, and meteor showers, I have no doubt of this. But there is a spiritual aspect to this as well. The stars of the heavens fell to the earth…what could this point to? No I definitly am not a Preterist, I just happen to believe that the actual celestial things whch are slated to occur, point to a spiritual reality. That is a far cry from "spiritualizing" them.
