also i re-read the part about the smooth formations that housed the souls of the dead... there's 4 of them, each for different groups
the lake of fire is for the Angels btw, not for normal sapiens humans, and they are locked there for over 10,000 years and by the timeline calculations i've seen, not the standard catholic bible ones, it was about 10,000 years ago when Enoch flew away to the sky to join the Angels in their migration to the stars, and the fallen angels are confined here, that means there has been a guard on this planet ever since that time
