Can you show me the evidence for it?
“In nothingness power finds its fill.
That is a holy spirit. The great holy spirit is the source of power.
Among these, light and darkness, the two great spirits.
Who came to exist at the same moment as the world.
But, the world was without form, a ephemeral existence.
Light and shadow, darkness and the light. Two existences that shall never interweave.
One day, the great spirit time was born.
The child of light and darkness.
And thus the world began to move.
The moving world spun, without purpose, around itself.
Inside the flowing currents of life and death,
Earth, Water, Fire, Wind, and Sky–these five great spirits were born.
And since then, these were the great eight spirits. Until the light consumes the world, erasing darkness. Until a new spirit is born, erasing all. Life and death, heralding the coming end of the world."
Here it states that when the Great Spirit of time was born the world began to move(This would mean that there were no time before the Great Spirit of Time came into being), but there was still an empty void without anything before the Great Spirits of the elements were born and created everything.
"One day, the great spirit time was born.
The child of light and darkness.
And thus the world began to move."
Great Spirit of time created Time.
"Who came to exist at the same moment as the world.
But, the world was without form, a ephemeral existence. "
There was still nothing even after the Great Spirits of light and dark were born, then time but there was still nothing until the Great Spirit of the Elements.
"The moving world spun, without purpose, around itself.
Inside the flowing currents of life and death,
Earth, Water, Fire, Wind, and Sky–these five great spirits were born."
Chapter 248:
"After that, I floated off into space, and witnessed the ending of the universe.]
-I couldn't quite understand what exactly Ciel was saying...
Did she witness the end of the universe? What was that supposed to mean....?"
uses universe when mentioning the end of space and time
Chapter 399:
"<<No. It will not affect the other dimensions. Only this universe will lose its progress and be returned to 0.>>
Oh. If it didn't affect the other worlds, then I could just leave it and return home..."
it mentions how the Mobius system would delete this universe(uses universe), and it wouldn't affect the the worlds(uses -s meaning plural).
from these we know that there are many universes inside Veldanava's world, and we know the Great Spirits helped create Veldanava's world.
(I don't really think Great Spirits should be type 2 concepts because we don't have enough info but ehhhhh)
For nonexistence type 2 it's really simple and I believe could be given to Rimuru.
Turn Null energy or Primordial energy existed before the World, Great Spirits, and even Veldanava. It existed before everything, before even the concepts that the Great Spirits are. Veldanava, as a true dragon, suddenly was born inside that nothingness, and existed there without any concepts. Rimuru is a true dragon, bam!
Although I don't think conceptual type 2 should be given, I know Non existence type 2 should.
