Although Matt.24:2 could... be seen as historical with the destruction of the temple in 70 A.D., that's not really the timing Jesus was pointing to, and His disciples understood that point too when they asked Him:
Matt 24:3
3 And as He sat upon the mount of Olives, the disciples came unto Him privately, saying, "Tell us, when shall these things be? and what shall be the sign of Thy coming, and of the end of the world?"
KJV
By that, they understood Him to be speaking of the time of the end, especially the Zechariah 14 events on the day of His return to Jerusalem, for they would have been familiar with that OT Scripture.
Just saying, "Well there's been no standing temple there since it was destroyed in 70 A.D.", is not enough to pass this off as already having been fulfilled.
The reason is because we already have signs today in the last couple of decades with the orthodox Jews in Jerusalem prepared to build another temple upon the Temple Mount, and start up the old covenant temple worship again. Even cornerstones have been cut and are ready. And the Jews have been doing DNA research to find Levite priests for the temple worship, the Sanhedrin has formed up again, and even some temple articles required have been made and are on display in Jerusalem.
Another reason is because in 70 A.D. no "abomination of desolation" (idol), which Jesus quoted from the Book of Daniel, was setup in that temple; instead that second temple burned down before the Romans could get control of it (per Jewish historian Josephus - 100 A.D.).
And yet another reason is, these signs Jesus gave in that Matt.24 Chapter parallel the six Seals of Revelation 6 about the end of this world, the last sign He gave being about His coming and gathering of His Church.
