Final answer:
In ancient Egypt, the religious practices and rituals were preserved in the temples, with hieroglyphics often used for communication. These were disrupted during the reign of pharaoh Akhenaten, but were eventually restored by succeeding pharaohs.
Step-by-step explanation:
Egyptian religion was primarily preserved in the massive temples dedicated to the Egyptian Gods. These temples, for example, the temple of Amun-Re at Thebes, played significant roles in the religious life of ancient Egypt. The temples housed sacred images of deities, were the sites where grand processions were carried out during festivals, and were also the residences of the priests. These priests were educated and could read and interpret hieroglyphics, the complex writing system of ancient Egypt.
However, a major shift occurred when Pharaoh Akhenaten, in an attempt to establish the worship of Aton, desecrated these temples. After his death, the subsequent Pharaohs, Smenkhkare and Tutankhamun, worked on restoring the old religious practices, repairing the temples, and erasing traces of Akhenaten's reign. But much of the original religious practices and scripts had already been destroyed and it took a significant time and effort to restore them to their old glory.
