Egyptians believed that the physical body was essential for the afterlife, where the soul would need a home because they viewed life as a continuation beyond death. This belief was rooted in their understanding of the soul, which consisted of multiple parts, including the "ka" (the life force), the "ba" (the personality), and the "akh" (the transformed spirit).
The preservation of the body through mummification was crucial, as they thought it would allow the ka to return to the body and ensure a stable existence in the afterlife. The elaborate tombs and burial practices, alongside the inclusion of artifacts, food, and treasures, reflected their belief that the deceased would continue to lead a life similar to that on Earth, necessitating a suitable environment. This led to the construction of pyramids and tombs that served as eternal homes for the souls of the departed, demonstrating their deep commitment to preparing for and honoring the afterlife.
