Hagoromo and Hamura were in a fight with Kaguya/Juubi just prior to the sealing, if I remember correctly.

They only won by sealing Kaguya/Juubi, which means Hagoromo couldn't have had the time to use Creation of All Things to separate the nine Bijuu from the Juubi and then seal the Juubi's physical body, the Demonic Statue of the Outer Path into the moon with his brother.
