okay...there is the possibllity of naruto being the son of the 4th...but the idea of naruto accually being the 4th cant work. reasons i say this is that, first there has to be a sacrifice to do this kinjutsu(forbidden technique). so no one was sacrificed and you cant say it was the 4th due to the terms of the god of death justu(and by the way the 4th's soul is not in the belly of the god of death, nor is the thirds....its the victims soul that is devoured and the user sacrifices their life....also oochimaru's almost summoned the 4th in the fight against the 3rd so once agian his soul couldnt have been devoured, *remember that*). also in the 2nd episode the third tells iruka that the fourth said that naruto is a hero and should be remember that away... meaning that the 4th was still alive even after he sealed the fox demon in him. also jirarya didnt teach kikashi with 4th.kikashi, the uchiha guy and the medical ninja chick were all trained by the 4th.check back through the episodes around the chuunin exams and youll see kikashi in his room, not sure which episode right off hand but there is a picture of him as a gennin with his team, right beside the picture of his current team with naruto, sasuke, and sakura.
