Is 600 bce a good date to end early time period of world history

Yes, that, I think is perfect.  When I think of early world history, I think about Babylonian times (before that would be Pre-History) to the founding of Rome. Then from the founding of Rome to the fall of Rome would be what I call the Mid-History.  After that would be Medival times all the way to the Renaissance and from then on, I consider it as modern history.  Of course, this will probably change in the future.  Plus, this is only the periods of history in Europe, Africa and the Middle East.

Idon’t understand a word going on right now lol
