Here's some research that could be related to this.
Awhile back I posted a thread entitled: "The Seven Earths". It is located here:
There are Seven core worlds that can be found in the Jewish Cabala, Islam, and Zoroastrianism. According to the Cabala they each have their own Suns.
According to Islamic writings, the closest one would take 500 years to travel to and the furthest out, the Seventh, around 3000 years. I have to ask
at what speed? They are separated by "unearthly waters", which I assume to mean the primordial waters of the great deep, aka Tehom. This wouldn't
mean literal water but the abyssal vacuum of space.
The Yezidis also have a tradition of Seven earths as well, where Melek Taus has been given dominion over them. Note that Melek Taus is thought of to
Note there is a clear distinction between these Seven core worlds and the Seven Heavens, which appear to be non terrestrial realms.
As for Gog and the Magog, Gog "himself" is the chief prince of the Magog. The Biblical references to him imply that he is one of the Sarim, or
angelic princes that rule over the nations.
Some people have interepreted Gog as being the same as Abaddon(literally destroyer), king of the Abyss and the abyssal "locust" horde. That would
make the abyssal locust horde the Magog.
Rereading Revelations 9 in light of this would impy that the chapter is about an apocalyptic extraterestrial invasion of earth.
What is also really interesting is that one sci fi show has already made the Magog into aliens.
In the show the Magog inhabit a Dyson Ring, a mobile home world built around an artificial star.
Their god and leader is known as the "Spirit of the Abyss", sometimes refered to as "The Darkness".
