The sentence that explains the significance of this story to ancient Egyptians is the following:
“From that day forward, the people of Egypt considered each pharaoh to be Horus in the form of a human”.
The story told is based on the myth of Osiris-Horus-Set and the last sentence is the one that indicates the meaning given to this myth by the Egyptian people, through the religion transmitted by its priests.
Basically this myth is the explanation that represents the source of authority and legitimacy of Pharaoh as King and God Sovereign of the Egyptian people.
Some of the causes can be less important than others, but determining their importance is hard since historians can't rely on experiments to determine cause and effect relationships the way scientists can. It's also difficult because events are in the past, and sometimes historians don't have much evidence to work with.
