Bartering and raiding. They never had a merchant system.
The first two battles were the Battles of Lexington and Concord, fought on April 19, 1775 and they were located in Massachusetts.
Here are my thoughts and responses as to what I come to know for these civilizations' achievements. I even checked my World History notes from last year...
1. Egyptians
2. Sumerians
3. Phoenicians
4. -This is debatable... We could argue early caveman or Sumerians made it, depends on what resource, textbook, or class material you are deriving this from. Maybe Hebrew because they developed Monotheism, belief in one deity.
5. Hittites
6. This is very difficult to elaborate on. Many civilizations had very strikingly similar achievements and reviewing my notes, I can't find anything to give an absolute civilization responsible for this. You'll have to guess.
7. Babylonian?
Sorry I couldn't help with #4, 6, and 7 that well. It's very difficult to answer.
