* First known agriculture: The region known as the Fertile Crescent is considered the birthplace of agriculture. This region includes parts of modern-day Iraq, but also extends into Syria, Jordan, Lebanon, Turkey, and Egypt. The earliest evidence of agriculture dates back to around 10,000 BCE in this region.
* First known written language: The first known written language, Sumerian cuneiform, developed in ancient Mesopotamia, which is located in present-day Iraq. It emerged around 3500 BCE.
Therefore, while Iraq is part of the region where both agriculture and written language originated, it's important to note that these developments were not solely confined to Iraq. The Fertile Crescent was a wider area where these crucial advancements occurred.
