Obito said Hagoromo removed the Ten-Tails from himself on his deathbed, created the 9 Tailed Beasts and sealed the remaining Demonic Statue into a Moon prison. Kurama said Hagoromo was kept alive thanks to the Demonic Statue after itself and the other Tailed Beasts were made, but it left him paralyzed. Then we are shown completely different version of the events, with young Hagoromo and Hamura sealing the Ten-Tails into a Moon, skipping the Jinchuuriki of it part and making the Tailed Beasts on deathbed part and not making it possible for Hagoromo to have been kept alive by Demonic Statue. Six Paths Chibaku Tensei rips the chakra out of the target, as shown with Kaguya. Hagoromo took in that chakra and technically became the Juubi Jinchuriki (for the same reason Minato is Kurama's too, even though it's only his Yin part).

Hagoromo somewhere along the line realized the (spirit) Juubi would regenerate when he dies. He also realizes he dies before he can accomplish splitting it. So he summons the Statue back from the moon and makes the Juubi complete, then splits it's chakra into Nine separate beasts. Either Hagoromo himself or Hamura ensures the Statue is returned to the moon.

It makes a lot of sense too. Madara could only summon the Gedo from the moon because Hagoromo already did it centuries before.
