Yet we remember the name and works of Homer, almost 3000 years old.

μνάσασθαί τινά φαιμι καὶ ἕτερον ἀμμέων

"I think men will remember us even hereafter."

We only have 2 books out of around 16 from Homer, so a lot has been lost already.

Let’s assume he was real. What’s the benefit to him that he’s remembered?

This is not a rhetorical question. Maybe some of your offspring has higher chances of survival if you’re remembered?

Yeah, except Homer is likely ahistorical.

And the Trojan Epic Cycle contained eight epic poems. We just only have two of them. We've also lost the rest of the epic poems. We have a fraction of what was considered great even 1,200 years ago.

we even remember Ea-Nasir
