what i was thinking is that some people say that the middle east was the birth place of the human race what if say the pacific islands where the birth palce of humans?
Assuming you're not a troll...
Hard to do. Read
Guns, Germs, and Steel by Jared Diamond for more information, but basically there's no way for the Pacific islands to provide the same benefits to civilization as the Fertile Crescent. The latter had an alluvial plain which made agriculture easy to discover and easy to practice, as well as a convenient staple crop (wheat) and domesticable animals to use as beasts of burden and thus create an economic surplus early on. In addition, humans did not have to migrate as far from Africa to reach what is now Iraq, meaning a civilization there is going to have a head start on any others. The Pacific islands lack all of these, and the west coast of North America has the Willamette valley, but still is disparate and lacks domesticates and a viable staple crop. Unless the primary civilization on earth has its capital in Rl'yeh, there's no way the Pacific can sustain the same population density as Europe, the Yellow River valley, the Fertile Crescent, et cetera.
