So Obito and Rin should be logically older than him, but Kishi decided against it. Got it. Thanks.

@Elveonora, yea, I think that Kishi just wanted to show how talented Kakashi as a kid was, but forgot the timeline at this completely, would explain the thing at the Obito Flashback in the Manga, when Minato's head was there engraved besides the other Hokage heads, although he became Hokage after Obito "died".
