Is that so much to ask?
I didn't nay say the scripts, I merely said that all it proves is that Lucas didn't write down "Episode IV A New Hope" on any of them until 1979.
It doesn't prove Lucas hadn't thought of that before that point in time.
So what if i give Lucas the benefit of the doubt? I just personally don't feel right in accusing someone of something based soley on the cynical assumptions of his detractors.
