Great question! I wrote my college thesis on this!

Kierkegaard saw the absurd(the inherently ridiculous relationship between the ambivalence of the universe and humanity's desire to find meaning) and thought that faith(in god specifically) was a way to reconcile these opposing ideas.

Camus on the other hand feels that faith is a sort of "easy way out"(grossly oversimplifying) and that in his mind, the best way to approach the absurd is with a full throated utter and complete acceptance of it. Face the absurdity with your head held high and laugh in its face, and then just try and be a good person. Realize that we're all in this together and really other people is what we have to make it all worth it.

Happy to answer other questions on this topic! Hope it helps!
