Looking for a novel that deals with the following topics: antinatalism, nihilism, gnosticism's demiurge.
It could be in any genre.
In short I want something that has a very pessimistic view on existance but it's deep, thought-provoking and a bit scientific.
The closest that I could get was Peter Watts: Blindsight.
I quote that is thought-provoking and similar in mood:
“When God became lonely he created man, or was it when man became lonely he created God.”
― Melanie Exler
An example: An impotent deity creates life in it's loneliness, as an artistic act, but it's creation is lonely as well, so they try to cope by also creating.
