Are you all listening to this stuff, where time and time again pitabread has made a similar claim, as well as something like "I/we don't understand science" (science meaning only their interpretations, conclusions of what the study of the natural world tells us). When, just as many times, I've asked him/them to simply prove it in an open discussion right here on the discussion boards, and as I recall I made the offer as simple and reasonable as possible. However, it was always followed by excuses, and links to elsewhere, not here as requested where the link can be discussed in detail as part of that proof, yet he still makes a claim like that.
Now don't get me wrong, false claims are par for the course when it come to dealing with evolutionist here, and that's my main point, these are the kind of absolutely untrue claims the whole of evolution is contrived of. We have that, and claims such as "science proves nothing" as a comeback to the request of prove evolution. IOW, if they can't answer the question, they attack the question itself in a desperate attempt to cover up the fact they cannot come close to proving evolution. Meaning, they themselves actually do know by now what the actual fact mean...they got nothing.
