Something confusing about Hagoromo, Hamura and Black Zetsu's creation

[chaos control]

Now, it is widely accepted at this point that Hagoromo had the six paths yang power (the sun seal) in his fight with the Juubi while Hamura had the six paths yin power (moon seal). However, we have also seen that Hagoromo has both seals as he gave both of them to Naruto and Sasuke and they both appeared on his hands when Naruto and Sasuke sealed Kaguya.

Now here is what I am wondering: Did Hagoromo actually have both seals during the fight with the juubi? If so, did Hamura really have the yin seal? If Hagoromo had both seals then what was the point of establishing Hamura (besides to give the Hyuuga clan an origin)? Also, if he had both seals then why couldn't he just seal Kaguya himself (without Hamura)? If Hagoromo didn't have both seals, then how did he eventually get them both?

Finally, I have been contemplating this one for awhile. When, why and how exactly did Hagoromo become the juubi's jinchuuriki? After all, With the bros together having both seals, they could have just used six paths chibaku tensei on the juubi and sealed Kaguya in the moon from the start. Also this question brings up some chronology issues about Black Zetsu's creation.

Black Zetsu said he was created just before Kaguya was sealed. However, we know that Black Zetsu was clearly there to witness the lives of Indra and Ashura (as he tempted Indra). Now Hagoromo was said to have created the moon on his death bed (or at least in his old age). This would have to be true if Hagoromo went most of his life as the juubi jinchuuriki. Having said that, Hagoromo was clearly not on his death bed in that panel when he was teaching Indra and Ashura ninshuu (which was still a time in which Black Zetsu existed). Therefore the creation of the moon (a.k.a Kaguya's sealing) would have had to take place at a much later time. However, Black Zetsu existed before this (as stated previously).

Therefore it is a little confusing in chronology when the manga says Black Zetsu was created just before Kaguya was sealed. The only logical explanation is that when he says the word "sealed", he meant when Kaguya was sealed inside of Hagoromo.

What do you guys think?

That confuse everyone , one month before but propably Hagoromo killed his brother , cut his arm and take moon seal.

What about ashura and indra already grown up in the time hago launching kaguya upto the sky. That is mean BZ flashback is when hago had split the juubi, indra and ashura is grown up, and the time BZ is born and not after hago and hamura finished a juubi.

juubi after getting sealed for the first time is only to depowered or sealed it power, the proof is when kaguya forehead is turning to moon and sun symbol. And then hamura or hago done the process to absorb juubi into hago body, and month after month and after all thing is done like creating a bijuus finally CT is used to sealed mazo as a moon and BZ witness that events.

Inconsistencies and Kishi wanted to wrap up Naruto quickly. Kaguya and BZ was just a means to end Madara and wrap up the Juubi to get to the conclusion.

Maybe hamura gave the seal to Hagoromo so he can go into hiding or something. The Hyuuga are secretive.
Hagoromo said that after he and hamura defeated the juubi, he sealed it in him. He probably wanted to seal the juubi in him so he can give people chakra for ninshu. BZ was most likely created after Hagoromo released the juubi to split it into the bijuu.BZ tempted indra after he wasn't chosen as the sages successor.
