Knight’s proposal in the OP was a very reasonable one – not at all unlike what SETI would love to have happen.You did. And several others have. But did he? I haven't seen it so I asked him. If he already has answered then he is free to ignore the question.
It wasn’t the answer that we all agreed on that was the problem, it was Knight’s hijacking our answer as support for his aberrant interpretation of what that answer then means.
