Yes, perhaps.
I think you missed my earlier post, though The problem with this argument is that pretty much EVERY story ever told is derived from something that came before it. Including almost everything Shakespreare wrote. Art never exists in a vacuum.
Even if we go back to one of the oldest written tales we know, The Odyssey, it existed as an evolving oral story for - likely - a few hundred years before it was ever written down.
Even in music, have you never heard how Yankee Doodle was repurposed? Or how we re-worded God Save the Queen?
You appear to be saying there's no such thing as evolution or redemption.
