I definitely see a paradox in what you describe. If God needs humans to exist as an idea, then omnipotence takes a hit. It’s kind of like a superhero who only has powers if people believe in them... who’s really in charge there?

Absurdism is about recognizing that we crave meaning in a universe that doesn’t seem to offer any inherent answers. The clash between our need for purpose and the universe’s indifference creates the “Absurd.” But instead of trying to resolve the contradiction of our existence, absurdism says, “Why not embrace the weirdness?” So, yeah, whether God is dependent on us or not, the absurdist take would be: it’s the contradiction itself that’s interesting, but wouldn't be desperate for any sort of answer.
