most likely the channels... the REAL archeologists wouldn't wanna say something so suddenly without complete proof of the fact...
there's still no-one certain on how any of the pyramids were ACTUALLY built. its still all theories and "possibilities"...
also a small item to consider... since when does a tv channel, with all their money and competition for ratings turn down any old "schlock" that they can palm off into the masses of the ignorant?!
most people are stupid and will watch anything that opens with the words "assassination, incest, megalomania, feuding families" because it sounds exciting, and its on TV so it MUST be true!
