In the 16th century, European explorers discovered cuneiform writing while adventuring in Iran and Iraq. These inscriptions were found on clay tablets, cylindrical pottery, and stone reliefs. After centuries of effort, cuneiform was successfully deciphered, revealing the brilliance of Sumerian culture. The Sumerians constructed complex irrigation systems, developed writing, and left behind significant cultural legacies such as the 'Epic of Gilgamesh.' Their civilization reached its peak 5,000 years ago, showcasing extraordinary creativity and organizational skills despite harsh environmental conditions.
