Yeah like, I'm kind of curious as to why neither Ada nor Daemon have aged... Like, it can't be a "part Otsutsuki" thing becuase Code aged and both Boruto and Kawaki aged despite being significantly more Otsutsuki than any of the cyborgs are.
A thing I've seen get brought up...

Ishiki's ten-tails was a seedling that he and Kaguya brought to earth.

...Why would they have brought two? The way the trees are presented in Bort is that tree sucks the life out of a planet over the course of a thousand years to mold it into chakra.

Uh, when we first told about the God Tree and the Rabbit Goddess we're told that the god tree had existed on earth for so long that it was believed to have created the world and people know that it sprouted a fruit every 1000 years which... Doesn't really square with what we later learn about how they work. We're also told that Kaguya was a traveler from a distant world who had been searching for the tree...

I think after learning about the true relationship between the Otsutukis and the God-Trees that everyone has either assumed that the story has been retconned or that Kaguya just lied about it to her children—it helps that most of wha we know about that era is an anime only filler arc that outright contradicts the manga several times(the manga had finished by then there was no excuse) and so it's easy to ignore it.

The assumption is just that she fed Ishiki's lower half to a seedling and that's where 'Her' God-Tree came from but... what if it was already there?

I mean, Ishiki's body was apparently on Earth and a wall shows that three pairs of Otsutsukis have come to Earth with the third pair being so old that their symbols are eroded and grown over.

And Momoshiki and Kinshiki's behavior suggests that they just leave the god tree behind when they're done with it...

So what if... what if the story wasn't a complete lie/retconned? Kaguya(and Ishiki) came to Earth looking for a good place to plant a god-tree only to find that there was one already there and it born fruit and Kaguya then decided to go for it and kill Ishiki to take the fruit for herself?

But... Life still existed on Earth... Even after Kaguya harvested the fruit the Earth still had life on it.

If Shibai and his unknown subordinate planted a Shnju on Earth eons ago and Shibai's ascension occurred while he was midway through eating the fuit. Half-eaten chakra fruit hits to ground, Shibai's subordinate like, I don't know, puts his vacated body in a mosoleam somewhere on Earth and leaves the Shinju and half-eaten fruit behind... And as the fruit decays the chakra still in it leaches back into the planet, restoring it to life, which prompts the Shinju to suck that life energy back up.

"conservation of energy" doesn't apply to chakra, you can in fac end up with more than yo started with as demonstrated not only by th fact that it's stated that the Earth has more energy to harvest now than it did in Kaguya's time but also just, basic Sage Mode—drawing in natural energy restores your regular chakra in addition to giving you more energy to work with. The fact that the tree was molding the energy it was drawing in into chakra(and that it had power of its own to work with) means that the energy of the fruit would be at least somewhat greater than that of the planet and everything on it.

So this process repeats, the tree draining the life out of the planet, forming a fruit which goes untouched and eventually falls off and decays returning the energy to the planet until eventually the planet has enough energy that the Tree just isn't able to drain enough to kill the planet anymore and complex life begins to evolve on it once again—possibly accelerated by the fact that the biological data of everything that ever lived or died on the planet is stored in the fruits.

By the time Kaguya is there there's enough of a surplus that it's theoretically possible to sustainably harvest the planet or at least harvest enough for a single fruit without killing everyone.

Just a theory.
Also, according to the Minato prequel oneshot, the Rasengan was originally called the "Halo Frozen Dessert Hair Whorl Jiraiya Twin Formula Sphere" until Minato was told that that was a dumb name. Kushina is the one who called it the Rasengan first.
