In 1980 when Empire cam out, you could by a folding poster thing. On the back was a load of info an shit!!
One had a piece about the Empire, and it stated there that the Stormtroopers were clones...
Also, Jimbo is correct in saying, if Goerge Lucas says they are Clones, then they are Clones.
They may not have been once, but they are now!
