Why did they make art in the walls in ancient Egypt?

Ancient Egyptians created art on walls primarily for religious and ceremonial purposes. These artworks often depicted gods, pharaohs, and scenes of daily life, intended to ensure a successful afterlife and please the deities. Additionally, wall art served as a means of documenting history and conveying social order, reinforcing the power of the pharaoh and the civilization's beliefs. The intricate designs and symbols were also believed to have protective qualities, safeguarding the tombs and the individuals buried within them.
