No, but it was a bad example because I was thinking only of the authorship point of view.

A better example would have been the complaint tablet to Ea-nāṣir. We're pretty sure it's real; there might still be people alive that remember it being discovered. But in a hundred years, people with gen AI have created museums of fake artifacts but plausible, can future people be sure? A good fraction of the US population today believes wildly untrue things about events happening in real time!
