Your minds could be fully settled that Naruto Uzumaki is the Child of the Prophecy, so hear my out. I think that Minato Namikaze still has a chance of being the Child of the Prophecy in which the Great Toad Sage had first mentioned to Jiraiya. Jiraiya found Minato’s natural genius to be something unique and suggested that he could be the Child of the Prophecy.
However after his death, Jiraiya settled on failure until he finally met Minato’s son, Naruto who possessed no unique powers or genius but something about him helped rekindle the task the Great Toad Sage gave Jiraiya. He grew up and after a number of years, we were completely sure that Naruto was the Child of the Prophecy who would bring harmony and peace to all nations. He gained a number of different powers, mostly using Kurama’s great chakra.
During the Fourth Ninja Shinobi War, we saw the power of the Edo Tensei come alive, a number of key characters were brought to life, for example Madara Uchiha, Hashirama and Tobirama Senju. At this point Minato was finally brought to life, thus rekindling the fact that Minato could still be saviour, he could use his powers in order to bring peace, that is until Orochimaru limits him. The pure fact that Minato is even alive could mean so, it could also interpret that Kishimoto is trying to lead us in a way to which we’re going to be mind blown!
Yes, these facts are not hard, therefore it is a possibility, and thus it could happen. I personally do want Minato to get this credit, we don’t know a lot about him, only what Kushina told us, and so it would be nice to see Minato also get this title, just like the Yellow Flash.
