What if God, or some other being, invented and placed pretend beings that are meant to challange our reactions, teach us a lesson, ect. I guess to an extent this might include “pretend” history that is taken at truth.
That God isn’t allowing people to be hurt since they don’t actually exist, or that people like Hitler weren’t actually a person but someone who was created to perform acts in order to push us towards a certain direction.
This idea is obviously self-centric since it denies the existance of others. To the extreme it would state that your entire life is a fabricated test. It puts all of those “why/how could someone do that” momments into a new light.
