Your saying it doesn't make it true, either. If "most folks" believe it, that doesn't make it true, either.
I’m not saying it to make it true, I’m pointing out that through most of history since the Iliad and Odyssey became known works it has been generally accepted that there probably was no Homer, that in fact he was just as much a legend as the characters “he” “wrote” about.
Unless he was.
It’s a debate that’s gone on for a long time

And by “a long time” I mean even Herodotus, who was solidly in the Homer camp, doubted all the works attributed to Homer were actually by him.
It’s actually a very complex question that will never be answered. Which makes it much much more interesting that the bland way you’re trying to make it certain.
