Muhammad, the 70 weeks of Daniel all happened about 2000 years ago.  It is history.   

The point of Daniel 9 was to give the Jews returning to Israel from Babylonian exile the opportunity to avoid a second exile if they turned to G-d.   The period began with the word going forth to rebuild Jerusalem (Cyrus) and the destruction of Jerusalem circa 68 CE.
