To show how dumb is that argument. “My ancestors from 2000 years ago lived there, therefore this land is mine” is as dumb as “my grandmother lived there, therefore this house is mine”. With the same reasoning, Italy could claim all the Mediterranean coast belongs to them. And if it’s from “God gave us this land”, Spain and Portugal divided the Earth (except Europe) for them “because God”. Does this mean Spain and Portugal can claim “their land” back?
