Let's assume that this world is really real and every being is an individual.
More than 90% are not human human. Human humans are on 8-kun because the world sucks at the moment.
"Don't be just a human. Be a human human."
Dang, preaching to an empty vacuum - pretty much.
or
Real = everyone has a POV life experience
Everyone = the human population
Real, meaning, everything exists all at the same time, and not just my POV experience.
Also, if only partial exists - meaning just a part of the world - it's not really real.
If a being ceases to exist for a duration of time for the sake of a "main character" (ex. distance - the being is far away), then this world is not real.
>Quantum mechanics and specifically the Double slit experiment would suggest that it doesn't exist.
Actually, the world should fare better for animals as well in the New World.
Paraphrasing:
"It will be the best for Gods; it will be great for humans; it will be good for animals."
How about the world is "designed"?
So it doesn't go out-of-place, or create an anomaly.
The designed world ensures a "main character" to have an anomaly-free life experience.
