I like reading various ancient literature because most are historical accounts and many offer insights to the nature of Man,  Sin, Principalities and Religion. Moses was Trained in Egyptian Wisdom. I believe it helped him understand men and various spiritual complexities. Here are some points of note:


A


There are countless places and countless "universes" ruled by various spiritual powers. I will call all of them and the entire thing a "time". This is because we are all existing side by side, so to say, at the same time. Because the black matter /space surrounding the universes cannot not be limited to a place.


B


There are many holy places or universes. Likewise, there are many unholy places in the heavens. Some unholy places mimic the holy ones. Their spiritual authority is complex with various cadre of Angels. 


C


When the bible refers to heaven, it is an actual place existing side by side with our universe, but currently inaccessible because of the powers that rule the earth. This is why Christ told his disciples in his last days ... am going where my father is ...; where am going ... you cannot go; ... am going to prepare a place for you ... The place he is going to prepare will be our heaven. There will be many others that have always existed. 


D


The earth(which was one time alive and pure like other heavenly realms) and the surrounding universe is a place of bondage, placed by powers of darkness. It is in deep slumber. Intense sleep. It has not always been like this. The earth has within it such power that would shake the existing spiritual realms when released. It is why the devil is so interested in humans. Man is part of the earth. He was created from the "dust" of the earth. This would explain the concept of the "new earth and new heaven" in the book of Revelation. 


E


The Princes .. The Principalities of the earth Descended from a different plane of existence. Not one of the Holy ones though. They are now bound to the earth. The rulers are descendent from the mixture of these Princes with the seed of men. Also earth bound, they are evil spirits inflicting harm on the earth. They remain evil. Remember, the giants procreated too. So authority is, first, by royal lineage, then, by age, or generation.

That said, the earth is littered with tribal people who believe their ancestors descendend from heaven. Don't be  rolling your eyeballs at these old folklore otherwise dismissed as myths of origin. Am guilty of this. Don't also be dismissive of people who swear that a certain mountain was their father. These giants were (or at least their bodies) destroyed in the floods. Their statutes were incomprehensible to modern civilization ... and their calcified remains litter the earth. They returned to the dust of the earth.


G
The word "generation" could be interpreted to mean the lifetime of either of the beings of the earth. The Descended Angels, Their offspring on earth, their offspring with men, or the lifetime of men. These vary from tens of thousands to tens. 


An age is greater in length. .. and ends with an extreme overhaul ... the kind that was caused by the descent of Angels on the earth. Or the creation of Adam an event, or the flood of Noah. In scientific terms, I believe the end of the flood brought the Ice Age .. as it is written, that God Caused a wind to blow over the water filled earth ... to create dry land for Noah. Some wind!! Mammoths were reportedly, frozen instantly! Kilometres of Ice sheets rose high to the north and south living only a small habitable area in the Sahara... Where Noah and his family survived ...

Interesting topic.
