I just took a look at your Chronology Causality paper and wish to echo what LSCatilina said. By the 22nd Century BCE the nation-states and the ruling elites of those nation-states will be completely from OTL due to hundreds of years of years of butterflies. An Assyrian or Babylonian may arise in an alt-history. However, as Cyrus the great won't exist in this world, neither will Alexander the Great, because long before the 4th century BCE Greece would indeed be affected by the change in the timeline.
What you say in your paper it spot on, "Our world is one of cause and effect. Our lives are molded by the events of the past, and our futures are only a reaction to the present, which is always changing. Even the smallest change in the past could have enormous repercussions in the present.
For example, in 1866 a 9 year old boy suffered a fractured skull in a carriage accident. He wasn't expected to survive, but he did. Imagine if young William Howard Taft had died in that accident.
Or this, which I've used in a TL, imagine the change to history resulting from Karl and Wilhelmine von Bismarck conceiving a child hours/days (minutes?) earlier or later than OTL and then, 40 weeks later (more or less) welcoming into the world their daughter Ottilia.
