Genesis 11:1
The Tower of Babel narrative begins by informing the reader that the whole earth had one language. This is odd considering what was stated in 10:5, 20 & 31. People typically try to get around the problem by assuming that the chronology of chapter 10 overlaps with the events of chapter 11, ignoring how forced that solution appears. The truth is that neither chapter 10 nor chapter 11 paint a realistic picture of how and why human migration actually occurs. Chapter 10 wants us to believe that people cleanly and uniformly spread out by families and settled according to their languages and cultures, thereby putting the cultural cart before the geographical horse. Chapter 11 wants us to believe that it would take divine intervention to get people to migrate instead of obvious factors like constraints on available resources, rivalries, instability, etc. Both ideas come from the imaginations of ancient people who had little understanding of things like cultural geography.
Interestingly enough, it seems that Native American mythology like that of the Iroquois comes closer to reality by suggesting that groups of people were first spread out and isolated from one another by the creator deity, the Holder of the Heavens, and then because of that cultural and geographic isolation their languages changed to be different from one another. This etiological myth for the origin of the differentiation of language has the added bonus of including some things we can actually observe when we look at how and why languages evolve over the centuries, unlike the Babel myth which relies solely on divine intervention.
