Final answer:
The Ben-Ben shaped stone in Egyptian mythology symbolizes the original mound where Ra appeared and brought light into the world. Pyramids were designed to echo this symbolism, representing the sun's rays and a path to the heavens.
Step-by-step explanation:
The Ben-Ben stone in Egyptian mythology symbolizes the original mound from which creation began. The Ben-Ben was associated with the god Ra, the sun god, who is said to have appeared on the mound and brought light into the world, marking the creation. The shape of the pyramids, akin to the rays of the sun, is a reflection of this solar reference and is thought to represent a solidified version of the sun's rays. Moreover, pyramids, such as the Step Pyramid of Djoser at Saqqara, were initially designed as a staircase to the sky, symbolizing a ramp for the pharaoh to ascend to the heavens, underscoring the link between the architectural design and the sacred symbol of the Ben-Ben.
