The idea is that ultimately there is no god or meaning in this world, but one should rebel against that meaningless and create our meaning. And he even says that accepting religion and god would be a failure instead of just accepting the absurd reality.

But in Sisyphus’ world, there literally are gods. The gods cursed Sisyphus and made his eternity just pushing up a rock, and he chooses to spite them by being happy instead of being upset like the gods hoped for.

There is no angry god to rebel against. No one cursed us with a spiteful purpose. So it seems weird to choose an allegory involving a fictional universe with existing inherent purpose to demonstrate why one should accept the real universe without inherent purpose.

That’s okay. I’ll still keep embracing that trash.
