None of these make sense to me. Our single universe seems like a definition of originality. the two following need further elaboration on your part, please.
It doesn't matter if it makes sense to you; what matters is your logic is flawed - and logic speaks for itself.
What's original about 'one universe' in the context of formats of existence?
There is nothing original about one universe, in that context.
There are many possible formats of existence that are, to you, void.
Is the universe is packed with enough content to preserve originality?
That's a different context - but yes - preserved within the atomic universe is lots of originality.
I
know the multi-verse exists, because it's the scientific progression that resulted in the creation of our universe.
If you knuckle it down to the very first existence, is likely not the big bang; ye of little faith might think otherwise existing in such a place with such a highly illogical image of the past; then you can predict that there is progression of simulation, evolution, it currently produces universe's like this one and that's all we know unless
some of us have deeper connections with 'up there'.
Do you think that this universe is for the pleasure of the species that exist within it, and it 'popped up randomly'?
It's not - species external to our universe may exploit this for science, or other.
Imagine all the scientific data that can be gained by creating such a universe - to you is null - but to me is real.
Obviously it was created to discover new ways to improve simulation as a whole.
Species has never been about one, and our universe is more likely one of many, and that is logic.
