Somewhere in the empty void of space, a lot of shining globes are floating and rotating around each other. These globes are known as proper universes in sci-fi terms, while immortal civilization calls them the lower worlds.
These uncountable lower worlds or universes are rotating on a predestined path under each immortal domain, or higher dimensions in sci-fi terms.
Inside one of the universes, a lot of clusters and superclusters are rotating around each other, carrying uncountable galaxies inside them.
They are uncountable because, each moment, millions of star systems and galaxies are destroyed and then created again from the same matter scattered through the universe.
"In such a galaxy and star system, there is a small blue planet with creatures like us who think we are knowers of everything and assume aliens will invade us like this; aliens would invade like that, which is an irony in itself."
