Christian not Arab Christian. Arabs are Muslims, and those hailing from Muslim lands. Arab Christians would be Christians than defected while in an Arab nation (underground Christians in Saudi Arabia for instance). You seem to be implying that Israel is an Arab country. It's
not. It's the homeland of the Jews, the birthplace of Christianity, and it's a country the Muslims have tried to subvert the culture of for the last 1400+ years.
History is relevant to other things, such as, if you'd read the article, you would notice that Muslims are effectively trying to act like the Temple never existed there. They are forbidding archaeology for the exact reason that had they dug any great distance, they would find alot of Jewish artifacts that would effectively disprove Muslim legitimacy for building on that site. I mean c'mon, Muhammad was never taken up to heaven there.
The Death of Muhammad
Muhammad died due to poisoning after attacking and conquering Jews while they were picking dates (no joke). He died in 632 AD. Years later, his followers came up with this story after they, an invading force, occupied the native land of the Jews (691 AD). It was basically like putting a flag on the moon and claiming it for the USA (okay, now the US owns the moon). The Dome of the Rock was built over the Temple, which fell in 70 AD and which the Jews had trouble rebuilding because of law this and custom that (they for instance have to reconvene the Sanhedrin which got disbanded).
This is why history matters, it sets the record straight, and stops lies from festering and enslaving people. It also explains why certain people hate each other, instead of "Oh those Jews are just evil." No, you took a dump on their holiest area of land.
Israel not Palestine. Christians not Arab Christians.
