Time Immemorial? You must mean the book From Time Immemorial by Joan Peters. While that's perhaps the single most common narrative people believe, it's full of myths that most historians have dispelled back in the 1990s. The author attempted to “prove” the laughable proposition that the land was uninhabited before Zionist immigration created the jobs that attracted Arabs from other regions. Much worse were the claims that the exodus of indigenous Palestinian people was due entirely to the orders of advancing Arab armies, who invaded the new Jewish state of Israel. The sad reality is that almost half of those expelled (300,000) were driven off their land before the war started (my parents included).

One would be much better off reading actual historical accounts the region: The Hundred Years War on Palestine (Rashid Khaldi) and The Ethnic Cleansing of Palestine (Ilan Pappe).
