(Well, I can trump that! My Mormon relatives tell me that they can trace my genealogy back way further than even the so-called "pre-existence!...see below)
Mormon "scripture" -- adhered to by True-believing Mormons: Man was also in the beginning with God. Intelligence, or the light of truth, was not created or made, neither indeed can be...For man is spirit. The elements are eternal and spirit... (Mormon Doctrine & Covenants 93:29,33)
Why, how "New Age-ish" of Joseph Smith to label us ALL as going back in existence to be 100% on par with God's "beginning!"
How pantheistic to say how "eternal" the elements were; and that the spirits of men & women could not be created!
But wait a minute.
If our genealogy goes back to premordial spirit slime & goo along w/other spirits & elements...why did we need a "Mom God" in heaven to have sex billions of times with the Mormon god in order to have billions of spirit-babies???
Well...are you thinkin' what I'm thinkin'?
Yup. Admit it...you thought of this before I did...
The Mormon god must have just been tellin' his wife she needed to have sex to keep churnin' out these spirit babies...knowin' all along, that the Mormon stork delivered them daily from the pre-mordial spirit slime & goo central!
I'm tellin' ya...But shh...(don't want to get the Mormon god in trouble over his Joseph Smith-like bedroom secrets)
