How did anubis come into being?

Anubis, the ancient Egyptian god associated with mummification and the afterlife, is believed to have originated from the fusion of various religious beliefs and practices in ancient Egypt. His portrayal as a jackal or a jackal-headed human likely stems from the scavenging behavior of jackals around cemeteries, symbolizing protection of the dead. In mythology, Anubis is often considered the son of Nephthys and Set, or in some accounts, Osiris. His role evolved over time, reflecting the changing beliefs about death and the afterlife in Egyptian culture.
