It has been pointed out that the Spirit hovering over Mary was the same Spirit that hovered over the waters in Genesis. Jesus was incarnated in the womb of the virgin ex nihilo. The womb of Mary was formless, void, and dark. The Spirit hovered, God spoke, and the Word became flesh.
But this works backwards as well.
The creation of the universe was a virgin birth. The virgin cosmos, formless, void, and dark, came to life by the hovering of the Spirit, God speaking, and the Word becoming flesh.
The heavens declare the glory of God, the Psalmist says: they are words that can be understood in every tongue, every language. They are living words of the Word of the Father.
Creation is itself incarnation, a lesser, derivative incarnation to be sure, but incarnation nevertheless.
