The Messiah's preexistent state before the creation of the world is asserted in the Book of Enoch (xlviii.

When the whole pleroma of preexistent souls in the world of the Sephiroth shall have descended and occupied human bodies and have passed their period of probation and have returned purified to the bosom of the infinite Source, then the soul of Messiah will descend from the region of souls; then the great Jubilee will commence.

If we try beginning with myths of the origin of the world, we frequently find that it owes its origin to the activity of preexistent supernatural beings.
