Hagoromo and Hamura sealed the Ten-Tails with using Yin/Yang seals, like the ones Sasuke and Naruto have right now on their hands, then Hagoromo used Chibaku Tensei to trap the Ten-Tails(which is Kaguya) in what is (or was) the moon.

How do you use Chibaku Tensei, the Rinnegan.

Who has the Rinnegan, Sasuke.

Problem solved.

Stop being silly.
