Hi Brother Hewitt, Here is some explanation from the Insight book on who the woman is and she is apparently heavenly but she still has children on earth.

It would follow logically and in harmony with the Scriptures that the “woman” of Genesis 3:15 would be a spiritual “woman.” And corresponding to the fact that the “bride,” or “wife,” of Christ is not an individual woman, but a composite one, made of many spiritual members (Re 21:9), the “woman” who brings forth God’s spiritual sons, God’s ‘wife’ (prophetically foretold in the words of Isaiah and Jeremiah as cited in the foregoing), would be made up of many spiritual persons. It would be a composite body of persons, an organization, a heavenly one.

Satan is shown later as persecuting the “woman” and making war with “the remaining ones of her seed.” (Re 12:13, 17) The “woman” being heavenly, and Satan by this time being hurled down to the earth (Re 12:7-9), he could not reach those heavenly persons of whom the “woman” was made up, but he could reach the remaining ones of her “seed,” her children, the brothers of Jesus Christ still on earth. In that way he persecuted the “woman.”
