EdenOne, it's so refreshing when someone defines atheism correctly instead of spouting that tiresome cliche, "atheists don't believe in God".
It seems to me that you actually are an atheist but that you're rather hesitant to accept the label, why would that be? Correct me if I'm wrong.
Bear in mind that even if every question around evolution could be answered to your satisfaction, and all but a few can be, that still wouldn't "[rule] out a supernatural / intelligent intervention", it's just that such an intervention isn't necessary and never has been.
