You might as well ask if Christianity would make any sense if Zoroastrianism never existed!
No duality of good and evil?
No angels?
No divine realm in the sky, instead of in the underworld?
All these influences popped up when old school Judaism bumped into the Magi caste of priests.
The Enochian school emerged… the Parisee were named after Persia (the Farsee/Parsee)… and the Essenes became the highest practice of “zoroastrian import” into Judaism.
The Transfiguration is not a hold-over from pre-Exile Jerusalem.
If you insist otherwise, the closest match to it is Tyre… with its mythology that a mortal throwing himself into a sacred fire “divinizes” the righteous!
