Also, even if all Eldians, and thus all Titans, in the world are dead and extinct, what about the Earth Devil? It could still create another kind of creature. Well, at first, this theory is what I thought was Zeke's and Eren's plan before the release of chapter 114. After this chapter, I was thinking that it was Eren's plan. And it still might be. But before that, he'll probably want to use the Rumbling.

And the Earth Devil... It's 100% a legend. There's no way such a being really exists in AoT's universe. Tbh, "Earth Devil" being just a mythological figure and not real is something that seems accurate for most of people. It is even said in the first sentences of its wiki page: "is a figure of Eldian mythology". Maybe the Devil is the personnification of something (The Path, The Coordinate, The Source of All Living Matter), but not an actual historical character.
