Sometime in the future they were able to take Sasuke's DNA.

They did this to create the most powerful human ever as Naruto & Sasuke are currently the most powerful chakra-users known so far and most accessible to the scientists.

Therefore Kawaki is a synthetic human

They may have also been jealous of Orochimaru's synthetic human, Mitsuki, so they wanted to prove that they were better

They unknown 3rd Otsutsuki granted Kawaki his power resulting in him getting the marks/sigils on his arm just like Momoshiki granted Boruto his marks/sigils

Boruto most likely met him after the Chunnin Exams and became friends with him

Unfortunately Kawaki gained a mind of his own and as a result of how he percieved the shinobi life, he wanted to end the era of shinobi as he didn't like it

He is highly likely to be a new character and not Iwabe or any other people that other theories suggest

He may also have his Senju hairstyle as a result of them maybe adding Hashirama's cells in to the mix, possibly allowing Kawaki to use Wood Release

P.S Tsunade's younger brother was called Nawaki Senju

Therefore we can expect Kawaki to be a worthy opponent for Boruto and it will be a battle as Naruto vs Pain or Naruto & Sasuke vs Kaguya if not better

I agree with most of what you said but in light of new information my think is this, he is genetically created from naruto and sasuke using their DNA which we all know in the narutoverse isn't hard to come by Judging by the multitude of edo tensei. He was developed by Kara I believe there know a lot about the history and origin of outsutsuki including kayuga and her two sons and about transmigration. So they knew by combining naruto's and sasuke's DNA they would essentially recreate hagoromo (whilst also bestowing on him other upgrades curse mark etc.) and making him a child/adolescent would allow them to manipulate and clones control him thereby making owners of potentially the most powerful weapon in the current time. This would also explain why in theory kawaki would be able to match naruto in power.

Now boruto I think boruto can be somewhat f a pseudo hagoromo in the sense that having naruto's DNA and some of his ninjutsu techs and then being trained by sasuke and having ninjutsu from him not to mention also being a descendant from hamura and having his unique jutsu also being trained by his mother could possibly explain why he would be most suited to challenge kawaki, it isn't necessarily his power levels but his skill set, just my two cents.
