Ok with all the things that have been going on as of late we have been given a few clues as to how the whole jincuhriki thing goes down

shows us that the biju can be sealed in objects and we know that they can be sealed in people.. but this also brings up .. why didn't Minato just use this to seal the fox in instead of his son?
Why was the Kyubi out of it's previous host in the first place?
Wasn't Madara behind the 9 tails attack 16 years ago?
IMHO I believe that Minato was the previous host somehow

we see the third Raikage used his son Bee to become the jinchuriki host
We know the Fourth Kazekage used Gaara to be the host
The only thing I don't get is how Madara got the Kyubi out of Minato to start his attack.. we do know that he has the jutsu for biju extraction since he has been collecting biju and st orig them in Gedo Mazo
Well what do you guys think?
