Well, it could be a result of a powerful jutsu gone wrong. Naruto attempts a new, experimental jutsu and instead of the expected outcome, it creates a Reality Marble within him. Or perhaps it's a genetic inheritance that he was unaware of until certain conditions were met. His Uzumaki bloodline might have some hidden traits related to the Reality Marble, and some event triggers its manifestation.
One way could be through some kind of ancient ninja art or scroll. Maybe Naruto discovers a long - lost scroll that details the creation and use of a Reality Marble. Another possibility is that he is bestowed with it by a powerful, mysterious entity. For example, a sage from an unknown land could see Naruto's potential and give him the Reality Marble as a means to protect the ninja world.
