1. Note that B.C. (Before Christ) & B.C.E (Before Common Era) always go from a greater number to 0. (The greater the number, the more in the past it is). On the other hand, A.D. (Anno Domini, or In the Year of our Lord), or C.E. (Common Era), goes from 0 greater.
In this case, order from earliest to latest:
- Ancient Egyptians (3100 - 1070 BCE)
- Ancient Greeks (800 - 338 BCE)
- Romans in Europe (509 BCE - 476 CE)
- Mayans in Central America (250 CE - 900 CE)
- Incas in Peru (1200 CE - 1532 CE)
- Aztecs in Mexico (1350 CE - 1521 CE)
2. It depends on where you live, but for the U.S.A, typically you would put at least the Mayans and Aztecs, while the Incas is a stretch, but still is justified as an answer.
3. Anna Mitchell-Hedges.
It was a special day, because it was Anna's 17th birthday, as well as them discovering a small crystal skull.
