I believe the Jews have lived continuously, in what is now called the land of Israel for almost 4000 years. Although the leadership of the Jewish people left Israel for Babylonia after the Romans crushed the revolt in a second century, some Jews remained in the land of Israel from that time forward. It is also important to acknowledge that Arab, predominantly. Muslim, people have been the majority in that area since the time of the Prophet. For diplomatic, political military reasons, any attempt to construct a Third Temple in a way that would interfere in any way, shape or form with the al-Aqsa mosque would be a guarantee of a general Middle East war, and possibly of a third world war. No one but a handful of fanatics among the Jewish people has any thought of building a Third Temple.
