Very well. This theory is intended to make you look at the game from a different perspective.
First of all, since Phenir confirmed that Black Goat was not initially in the game, which is also implied by

, it means that originally there was no accent on space beings and space gods in the game.
They existed as a primordial concept in the Red Hood's Woods, and were grown into something more later.
For example, the Hollowed Serpent is probably what we can see now as a Serpent God Yig in the BS2.
It is concerning, isn't it? Now, what is next...
A bit different story with a BS1. Originally BS1 was about a dying world, filled with a changed fairy tales and ruled by a cruel god Mary Sue. At some point she got tired of granting wishes to people, because they are greedy morons who kill each other. She decided to change the world.
Now now... I am aware that in BS2, memories tell us that Mary Sue teleports people into her world, rather than change existing one. Or everything is just a never ending dream? As you can see there is no straight answer, so, let me continue.
What is concerning about Mary Sue? Her words. In the ending C, her words about the world going still even if Grimm defeats her is absolute truth and
she is aware of it. I must remind you that Black Goat didn't exist at that moment and there was no ending D.
Since she is an aware being and absolute Creator, who also created Red Hood and her world of nightmares, including primordial concept for future gods (including characters, such as Catherine and Jabberwock), it would be not surprising if she add something new into existing frozen world. Despite what the information from BS2 implies about gods enjoying repetition, Mary Sue can get bored of it. You will see that if you lose to Mary Sue (Why did she use my name instead of Grimm's? Is she aware of player?)
Grimm lost to her so many times, that you can imagine her changing her mind and deciding to change the ending and let you kill her.
After that, she would get bored again and think of a new world. She decide to add Black Goat of The Woods and The Thousand Young and ending D, as a transition into a new world, with previously unrealized concept with space gods and space beings.
"But she is her mother!" you would say? Then I will say that, creating fake backgrounds and families is Mary Sue's specialization.
If Black Goat is Mary's mother, then Elizabeth Bathory is a mother of Red Hood as well. Mary Sue has no family, she created it.
Yes, I didn't prove anything, but perhaps just shown you a schizo point of view.
And yet, if Mary Sue is a Toro's self insert, would my theory make sense?
Someone: No, because in BS2 Mary Sue lost her powers and was changed/renamed.
Hmm... isn't it weird that despite anything Mary Sue survives? Isn't it weird that Mary Sue's identity has no place among space gods or rather there is no straight clarification?
Isn't it weird that Mabel, the oldest, the wisest, the most powerful god is dumb like Mary Sue and cries like a child when she loses in chess?
Isn't it weird that Mary Sue is looking at
YOU in the H ending?
Isn't it weird that the next game will be in the underground city, which is considered to be the Underworld by some people, because that's where you'd expect to see
Dead Red Hood?
Isn't it weird that Elysium belongs to Mary Sue?
Isn't it weird that if you google what Elysium is, you will find out that it is afterlife or Underworld?
...
What do you think about it, people? But, don't take it too seriously, it's just probably my schizo ramblings.
