Are you serious? How do you think the clay pot ended up being recovered by an archeologist? There's pretty much two ways...

You should look up some TikTok creators from Egypt, there is plenty of great stuff out there.

The basic premise of your argument as I understand it is that art is something you see in museums or art is something that has been gated by age or by scholars or by "cultural significance". This is not how art works, some great works were discovered long after the artist had died. TikTok creators create art, some of it good, some of it bad, but it's art all the same.
