so how i see it is that RA created a world and possibly countless worlds...
these worlds could have countless spatial dimensions maybe, but probably not.
the void and other places that isn't "the world" is of a higher existence than the world the humans live in. Ra could even see the world he created as a comic book ect.
EOS Lessa is even above Ra and Dark Lessa who both exist above the human world. He is also able to control "balance" which dictates everything in existence.
