Once again God's seems to be concerned about something. Such as after the fall He prevented them from eating of the tree of life and now keep them from getting too prideful in their ways! Lust of the flesh, lust of the eyes and boastful pride is from the world! Their point in building this tower was to make a name for themselves otherwise we will be scattered abroad over the face of the whole earth! God wanted them to be fruitful and multiply and populate the entire Earth! Once again man goes their own way and rebels against God's plan! Of coarse God improvises! :)
