I asked for proof, not an opinion on what you think is transpiring in the manga. Kabuto stated the Sharingan can evolve into Rinnegan. This is fact. What you think Madara says is wrong, is irrelevant unless the words that came from his lips were "You're wrong about the Sharingan turning into Rinnegan". Actually, after re-reading the chapter, he states "Don't misunderstand, this power wasn't created by you". All that says is Kabuto didn't create the power Madara holds, according to Madara. So again, the Manga is right until proven wrong.

Whether this means you need Sharingan to get Rinnegan is a whole different story. Momoshiki doesn't seem to have Sharingan. However, Urashiki does seem to have the same Rinnegan as Sasuke thus by some people's logic here, has a Mangekyo since that is what the tomoes represent?
