:::The Kingdom of Judah is not a mythical land, there are enough historical and archaeological evidences to prove its existence. Also, almost none of the Jews, and very few non-Jews, disagree with the claim that Jews have their roots in the Kingdom of Judah. It is very hard to prove this connection (just as it is hard to prove the connection between contemporary Egyptians and ancient Egyptians, or between Contemporary Greeks and ancient Hellenic people), and yet in these cases strong traditions count too. As for the term Eretz Yisrael - it is simply a common Jewish/Hebrew term for the region known otherwise (since the mid-2nd century C.E.) as Palestine.
