I gather you are discussing poetry or religion, as things like science can't answer that sort of why. We can't scientifically explain why the universe exists, it isn't something science can even attempt. We have a difficult enough time on how. I don't know that this is a problem.
AI is in its infancy. Its abilities will grow, especially as quantum computing comes online. Right now we hamstring AI, the corporations don't want to have it say things that may scare off investors or advertisers. So if asked the question "What is the meaning of life" it is programmed to give the "some say, others say" answer. That safety rail won't always be there. There is no reason a computer can't compare various origin stories and come up with one that it believes is at least minimally more likely. I don't see a reason they can't take parts of stories and integrate into a new one.
Once it gets quantum abilities, and the guardrails come down, I think we'll see huge moves toward AGI. AI can right now write stories/poems, paint, write music. It is only going to get better.
