No UFO's in the UB?
This is quoted from your book - no extrapolations: (my emphasis)
2. Transit of the Planetary Adams
51:2.1 Upon receipt of the news that another inhabited world has attained the height of physical evolution, the System Sovereign convenes the corps of Material Sons and Daughters on the system capital; and following the discussion of the needs of such an evolutionary world, two of the volunteering group — an Adam and an Eve of the senior corps of Material Sons — are selected to undertake the adventure, to submit to the deep sleep preparatory to being enseraphimed and transported from their home of associated service to the new realm of new opportunities and new dangers.
Now, perhaps I shouldn't have used the term UFO. Perhaps I should have used the term spaceship or superhypeinterstellartraveling device or whatever. But somehow your "Adam & Eve" get from one place in space to a different place in space.
Oooops, I'm wrong again. I just did a little further reading: (my emphasis)
51:2.2 Adams and Eves are semimaterial creatures and, as such, are not transportable by seraphim. They must undergo dematerialization on the system capital before they can be enseraphimed for transport to the world of assignment. The transport seraphim are able to effect such changes in the Material Sons and in other semimaterial beings as enable them to be enseraphimed and thus to be transported through space from one world or system to another. About three days of standard time are consumed in this transport preparation, and it requires the co-operation of a Life Carrier to restore such a dematerialized creature to normal existence upon arrival at the end of the seraphic-transport journey.
It's more like a Star Trek "beam them over" concept. But then, how does the Life Carrier get here?
No sci-fi stuff there huh? Are you sure L. Ron Hubbard didn't write the Blue Book?
