Such is only a chart-depiction of the the Isle of Paradise and central divine universe as revealed in the UB. As one learns the descriptions better, they can relate to such charts. The Isle of Paradise is 'at' the very epi-center of the Grand Universe. All creation evolves, emenates from and is maintained from that divine center, wherein also the Paradise Trinity dwells. Remember,...'God' alone is the 'heart' of all reality, the source of all creation.
The UB has no association with UFO's as entertained in the minds of pop-culture, so your childish correlation with the book with UFO's is misplaced, besides 'mistaken'.
There are transport seraphim and other angelic beings that assist in transporting spirit-beings or souls from one location to another, but I don't believe they use metallic materials or 'technology' for such acts. Again,..there are no mention of UFO's or little green men in the UB....AT ALL. All movements or transportation techniques in the mansion-worlds beyond (the spirit-worlds) are done by spiritual means or angelic assistance.
Ufology and different alien humanoid races within the local galaxies or universe systems as known on our world from the early 20th century is an entirely different field and study all its own. I should know, I had a thread on 'ET Theology', dealing with Ufology and physical/psychic contacts and the spiritual teaching transmissions from these various sources.
Most of the higher teachings all contain common universal truth-principles concerning energy-thought-consciousness, while some data may be more trustworthy or tenable than others,....its very much the same as in the field of 'theology', with all its variations of doctrine, denominations, cultural dispositions...further conditioned by soul development. There are various stages or levels in the evolution of life. This is basic metaphysics dear
