If we combine both versions, it somewhat makes sense:
 * Hagoromo and Hamura perform SP:CT on Kaguya (Jubi)
 * she turns into Gedo Mazo as her chakra gets extracted in the process
 * said chakra is sealed into Hagoromo
 * sometime later, Hagoromo extracts said chakra from himself, separates it into 9 parts and gives life to each with creation of all things
 * Hagoromo summons Gedo Mazo from the Moon, seals it into himself to stay alive
 * Hagoromo then sends Gedo Mazo back to the Moon when he decides that it's his time to die
