You did misrepresent TIA's comments, in an apparent effort to re-align them to your own agenda, but at least you've addressed that now. As for science always being provisional, well it's one of those statements that doesn't actually state very much. I suppose s/he means the findings of science, but I wouldn't be knowing. There is science and science. I'm not going to accept that it is always impossible for science to reach the truth. In terms of elucidating the process of evolution, I think science has got there - in the general thrust. Not in the detail, of course. If anyone thinks that evolution does not occur, let them produce the evidence that overthrows all the evidence we have which says it does occur. That's my line and I'm sticking to it.
