just a suggestion but if you're writing about "the ancient world" please don't include societies that existed from like 1300 to 1521

AZTECS AND INCAS WERE NOT ANCIENT I WILL DIE ON THIS HILL

The Americas have genuinely ancient histories also!!!! Tell me why you talk about Rome and Greece and Sumer and the Qin Dynasty and Middle Kingdom Egypt but you've never heard of the Moche or Chavín, the Olmec or the Classical Maya city-states, or even Poverty Point or the Hopewell Interaction Network, or maybe the ancient Tsimshian city of Temlaxam????
