Forum:Sephiroth, Cloud's Nodody???

OK, so I've been working on this since 05. I personally beleive that Sephiroth is Cloud's Nobody... or maybe his Heartless in fleshy form. The key to this is Sephiroth and Clouds meeting where he says to Cloud "I am you." Weither or not he ment that metaporhicly or seriously has yet to be determined, but I myself took it to ment that Cloud at some point might have become a Heartless, saved from the darkness by Tifa or Aerith or even Hades (due to there workings in KH1.) I have more to this theroy, but it's all very sepculative. If anyone has support to this, PLEASE help me!
