How did the Jews lose their homeland in the first place?

A few empires over a number of centuries expelled the Jews on different occasions from Israel. These included the Achaemenid Empire (Persian) under Cyrus the Great, then the Macedonians under Alexander. Later, the Romans, following the Jewish–Roman wars of 66–136 CE. These events, based on religious/political divisions resulted in a long period of violence, enslavement, expulsion, displacement, forced conversion, and forced migration against the local Jewish population by the Roman Empire (and successor Byzantine State), beginning the Jewish diaspora.

I'm guessing someone will debate this, because so much is based on myth and unfounded Biblical references regarding Moses and the expulsion of the Israelites from Egypt, the Exodus to the Promised Land in the 13th Century BCE, etc...etc...
