Nazareth was in the Galilee near Mt. Carmel, one of many ancient Essene communities located in Palestine as well as in Egypt, Iraq, India, Persia, etc.<quoted text>
shhh...don`t tell `them` but there is no historical record of a Nazareth existing until the end of the first century CE.
"In Phoenicia he (Pythagoras) conversed with the prophets who were the descendants of Moses the physiologist, and with many others, as well as the local heirophants .... After gaining all he could from the Phoenician Mysteries, he found that they had originated from the sacred rites of Egypt, forming as it were an Egyptian colony.... On the Phoenician coast under Mt. Carmel, where, in the Temple on the peak, Pythagoras for the most part had dwelt in solitude ... Mount Carmel, which they knew to be more sacred than other mountains, and quite inaccessible to the vulgar..."
(Life of Pythagoras by Iamblichus)
Mt. Carmel was considered holy ground by the Essenes and no building construction was allowed, only impermanent structures like tents and huts, so there wouldn't have been any building sites to be excavated by archaeologists except for the Mt. Carmel temple site which was located in 1929.
