Homer describes Thebes as a city of a hundred of doors. This is the name given by the Greeks to this city of Egypt.
Herodotus, who visited Egypt and Thebes, is very precise about its location: From Heliopolis to Thebes there are 9 days of sailing, ie 4860 stadiums. From the sea to Thebes there are 6120 stadia and from Thebes of Elephantine, 1800 stadiums. He witnessed a considerable amount of tombs and statues, many made in wood.
The translation of hieroglyphs allowed to recover the Egyptian names of this city, the most used were Waset, meaning "powerful" and Niout, "the city". The quantity of monuments still visitable does not allow doubt about this triple designation. The Neo-Assyrian texts confirm the role of Thebes, which served as a refuge during the Assyrian expeditions in the Nile Delta.
This is essentially during the New Kingdom that the city have its largest growth, in particular due to its role as capital of the Egyptian Empire and the presence of the Valley of the Kings.
However, the contours of the ancient city, and its many other names, are not sure. Most historians think that Thebes was Luxor, Karnak and the mortuary complex on the west bank of the Nile.

My notes of veracity :
Thebes was the current cities of Luxor and Karnak: 5/5
Waset and Niout are the hieroglyphic names of Thebes: 4/5
