In the previous posting, I argued that science needs some independent information about the designers before it can use an intelligent cause as part of an explanation. For as I noted, the science of archaeology and forensics rely extensively on our knowledge about humans. But there is one exception and Bilbo raised it:
Further, if SETI ever received the wished for radio signal, that would be considered sufficient evidence of a designer, even though we had no other independent evidence for one. And even if Mike wouldn’t consider SETI to be science, I think most scientists would.
Before getting to this point, to set the stage, it would help tremendously if you read how SETI replies to this argument and also read some of my own observations.
