But speaking of bad science:

In Discovery Channel's RAMESES: WRATH OF GOD OR MAN?, a Find in a Massive Tomb Could Be a Crown Prince Who Provides Ties to the Story of Exodus.

This kind of archaeology should have really died with 19th century.

The Exodus story is a myth. Even these folks don´t believe in the biblical account, but they seem to have a need to believe in what we could call an "Exodus light" scenario.

These kind of stories of decades long wanderings of peoples in a search of a homeland are not that uncommon, especially in Mesoamerica, and are more symbolical than historical in account. Even in Western Europe the aristocrats long held strong in belief that they were descendent from foreign, German conquerors, which gave them right to rule over the "native" population.
The Exodus story also connects the people of the kingdom of Judea with one of the most powerful states in the world known to them, Egypt - which was partly responsible for the destruction of the kingdom as it supported their rebellions against Babylonia, after Egypt had lost the battle over Syria and Palestine to Babylonia in the years after the fall of the Assyrian empire in 612 BCE - like the story of Abraham connects them with the major cultural and religious center of Ur, in Mesopotamia. The stories of mythical kings like David and Solomon then gave the kingdom - which had lived in the shadow of the more powerful northern kingdom of Samaria, now known as Israel, until that kingdom´s destruction by Assyria in 721 BCE - a great, glorious past, which could be used to rally people "around the flag", so to say, and used as a model for the future of the kingdom.
