The writing system you're referring to is called Cuneiform, which was developed by the Sumerians in ancient Mesopotamia around 3200 BCE. It used wedge-shaped symbols and was employed for various purposes, including record-keeping, literature, and artistic expression. Ziggurats, on the other hand, were massive structures built for religious purposes, and are not a writing system. The Alphabet refers to a later development in writing systems and Hieroglyphics pertains to the ancient Egyptian writing system.
