Why was a ziggurat made terraces?

Ziggurats were built with terraces to create a multi-level structure that symbolized a connection between the earth and the heavens. The tiered design allowed for greater elevation, making it easier for priests and worshippers to reach the sacred spaces at the top, which were believed to be closer to the gods. Additionally, the terraces provided stability and support for the massive structures, helping to distribute their weight effectively. Overall, the terraced design was both functional and symbolic, reflecting the religious and cultural significance of these monumental edifices.
