The Palestinian Information Center has posted this timeline of the history of Jerusalem.
For some strange, inexplicable reason, it only begins in the year 638, despite Jerusalem being around for over 4,000 years.

Obviously, it won’t go back before the Islamic conquest, because it would show some really inconvenient (Jewish) history that would destroy the entire premise of this infographic.
But what is telling is the fact they don’t go back regardless, given palestinian claims of being descended from the Canaanites/Jebusties/Philistines (or perhaps the Flintstones).
I guess even the Palestinian Information Center doesn’t believe that sh*t.
