According to Madara, there were clans fighting each other BEFORE the eating of the Fruit of the God Tree, therefore some clans outdate chakra use.
There hasn't been mention of the Princess, or her Son's Race/Clan specifically anywhere. Therefore if Senju and whomever came from either Son, they happened after some other clans had been rocking for a while.
The Uzimaki's, Hyuugas, Uchiha's, or Senju's beginnings have never been told. No one knows, theyre are so many holes in this shit it gives me a headache. Its a puzzle that won't match, it can't, its too broken in the first place.
Since all 4 are by design 'chakra' by some means users, shouldn't they have all come from the time the fruit was eaten, thereafter? Prior to the eating of the fruit, they're weren't any chakra users, see... busted, broke, fucked, stupid, retardedly bad.
