Who invented the door?

The original "door," in the Germanic languages, of which English is one, was the flap of a tent or a hut. It was opened by lifting it upward.

In English we say, "Open UP the door," and the Germans say, "machen die Tuer AUF." ("Auf" means "up," in German.)

The Hebrew letter "Daleth" is related to the word for "door," and the Greek letter "Delta" is derived from its Phoenician cognate. The letter Delta has the triangle shape of the flap of a tent.

The Delta of the Nile got its name from its triangle shape, and because it's the "door" of the river, which we today call its "mouth."

Since the most primitive people have "doors," in the sense of flaps to their tents, huts or whatever else they may live in, the door in that sense was invented before the coming of any advanced civilization, whether Egyptian, Sumerian or otherwise.

Og the caveman put a rock in front of his cave to keep the animals out. Really no one knows who "invented" the door. It's far too old for that.
