Was Jared Diamond on track with his theory of "geographic luck"?

               Jared Diamond was on track with his theory of geographic luck. All of the first civilizations were hunters and gatherers. Geographic luck occurred in some places more than it occurred in others. The first agricultural civilization began in the Fertile Crescent. The Fertile Crescent is between Southwestern Asia and Northeast Africa. The farmers in the Fertile Crescent could depend on rainfall there. On the other side of the crescent where they’re much rainfall the farmers learned how to use the rivers for irrigation. Them being able to grow crops was the reason of the wealth for the world’s first civilization. In Papua New Guinea they didn’t have the good fertilization for growing crops like the Fertile Crescent. They’re lands weren’t as smooth so it was harder to grow things. Like Jared Diamond says it depends on where the civilization is located. If it’s a good location the civilization will grow but, if bad then they will not develop as well as the other civilization.
