I would submit that this "ancient tablet" is probably another sensationalist scam, as is clearly indicated by the facts

(1) that no specific information is available on its provenance and

(2) that no details are provided on carbon dating of the ink.

As such, this "news" brings to mind the faked Lost-Tomb-of-Jesus "documentary" designed to make a profit off of people's fascination with the "real" Jesus, as well as the larger scandal of the biased and misleading way the Dead Sea scrolls are being presented in museum exhibits around the world, with an antisemitic expression appearing on a government-run North Carolina museum's website. See, e.g.,
