IOW, no proof.
I do not consider proof to be the be-all and end-all of science. It is only one among many tools science can use to arrive at knowledge. If proof is all you expect of science, then you expect too much.
I do.
I expect that someone who makes absolute claims should provide the evidence that proves what they're saying is true.
Intelligent Design is all about faith, which by definition, is about believing in the absence of proof.
Well, since you are of the belief that science strictly entails absolute claims, and science by nature cannot make them except in rare cases, it seems we will not agree on this. That's okay.
