My favourite that kinda falls in that category is that a “designed world / controlled universe” failed; was about to be completely destroyed. they realized it soon enough, so they encoded…encrypted ALL their knowledge into different media (dna, quantum stuff, etc. and idk) then put that into meteorites etc. and catapulted it out in all directions of the great nothingness, in the hopes that at some point it will land somewhere where it can cause a chain reaction (evolution) that will lead to a being, that is capable to restore the encoded knowledge.
