The evolution of a way of speech

Now: "All roads lead to Rome"

During the roman empire: "As we Romans are the only ones who know how to build proper roads, we have made them all lead to Rome"

(Bonus: Civilization-version: "Only the Romans have discovered roads")

In the stone age: "All paths lead to cave"

In the jurassic period: "If we pterodactyls shall ever become extinct and a species named homo sapiens shall evolve, who will build a group of houses and call it Rome, a fair amount of paths will most certainly lead to this place"
