I haven't read the entire thread here, so if this has already been said, please excuse the repetition.

I generally agree with your assessment of the "debunking" of Sitchin's work, and I do think Mr. Sitchin's translations were for the most part correct, so I won't argue with that bit. However, based on my own study of the Electric Universe theory as well as the evidence from the Deep Impact probe, your statement that "comets...are water" is most likely factually incorrect.
