The server ate my latest lovely reply, so this will, unfortunately, be briefer.
I have precious little time to engage in constructive dialogue, and, as I am no expert in theology, philosophy, evolutionary biology, or paleology, my responses would require extensive reference to othe materials, mostly electronic, to compose. As they are better stated and more accurate than anything I would produce as well as generally electronically available, it would be best to just encourage you to read them on your own. I'm sure you can find them. The OP asked about EO and evolution and I can't let the OP get away with the impression that there is only one option, the creationist option that can't believe the Earth is billions of years old or that there was any kind of death before approximately 7000 years ago, give or take a few thousand, at the Fall. It is simply by no means the only view.
My comment about the fever swamps was more directed at jckstraw and his sources than at Chesterton, as he is, after all, mostly a 20th century figure. A better response to Chesteron is more like, "And?" He states a few things most scientists don't fail to consider and seriously underestimates the process and results of the scientific enterprise. Perhaps some people then were deserving of his bluster, and at other points his response to evolutionism are quite handy, but here he really doesn't have any purchase. So he's just plain wrong here. He's quite right generally that scientism is a bad thing. Perhaps I was a bit too strong there - but I don't doubt his tenor would change quite a lot if he were around today, as there are decades more research into the matter under discussion, so his point there is simply not relevant today, at least not as a bludgeon against all of scientific endeavour in paleology.
