Humana is Earth, just with a massively different geography. The five continents are: Eumeria, Isani, Gamo, East Gamo, and OTL Antarctica.
Humans appeared around 4 MYA as australiopithecus. However, unlike OTL, humans became much more advanced at a quicker rate. Civilization developed at 8,000 BC, not 3,000 BC. By now (1000 BC), Humans have reached OTL 21st century technologies. Humana is mostly peaceful, and unlike OTL, there was only 1 World War. The many nations were combined into several large nations some spanning CONTINENTS. This will deal with all the nations of Humana.
