The Catholic Douay-Rheims Holy Bible copywritten and published before 1962 has the correct wording of Genesis 3:15
3:15. I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.
"The smoke of satan" entered the Catholic church during the Vatican 2 council and changed She to He.
She is none other than the Blessed Holy Queen of the Universe, Mother of God, The Blessed Holy Virgin Mary.
