It's natural for languages to change over time so, just like Old English is an ancestor of modern English, all other natural languages have older forms as well.

They all have to some extent. English is a little special in that it had more waves of influence than most as various groups moved to the island each leaving their linguistic mark. You can think of the British of antiquity, then the Romans, Angles, Jutes, Saxons, Vikings, Normans, and eventually French from the courts of Europe.
