Far, far away—whether in physical distance or in metaphysical dimension, we make no claims—and long, long ago, you and I were born as spirit children of God and, naturally, a Goddess, actual beings of glorified human form and substance.

Time on that planet-star, our Kolob-blessed home, was unmeasured and largely irrelevant. Irrelevant but for our date with destiny.
