Egyptians believe in the afterlife. Pyramids are built for religious purposes. In ancient times, especially in Egypt, people thought that there was life after death. Pyramids are made to serve as burial sites of Egyptians when they die. Afterlife on earth, a second life will resurrect as an ancient belief. The second self, called ka was believed to emerge when people die. Once the physical body left the earth, ka then joins eternal life. Ancient Egyptians constructed the pyramids to prepare their loved ones for eternal life. Most of the greatest and tallest pyramids in Egypt were made for their leaders and rulers. They made sure that the second life must be abundant. They put treasures and amulets in the coffin as they believe that the dead can bring these to the afterlife. The infamous pyramids in Egypt are found in Giza. The smaller ones were at the Nile Valley. Ancient Egyptians also honour one of their greatest rulers as they build Sphinx near the site. The Sphinx was sculpted to stand watch over the pyramid and burial chamber. The human and lion sculpture of the Great Sphinx of Giza showed duality, human and divine.
