The Sumerians were the first people to use the ziggurat shape for religious structures.

To find the answer to your question, we can start by looking at the development of ancient civilizations and their religious structures. The Sumerians were one of the earliest known civilizations in ancient Mesopotamia, located in modern-day southern Iraq. They thrived from approximately 4500 BCE to 1900 BCE.

The architectural style associated with Sumerian religious structures was known as "ziggurat." A ziggurat is a stepped pyramid-like structure consisting of multiple levels, with each level getting smaller as it reaches the top. It represents a fundamental form of Sumerian architecture, primarily used for religious purposes, such as temples or shrines dedicated to their gods and goddesses.

To summarize, the Sumerians were indeed the first people known to use the ziggurat shape for religious structures.
