You say you didn't budge on your creationism, but that's not surprising because Darwin wasn't actually attacking creationism, he was just making a case for evolution. I'm curious..if this book didn't convince you about evolution, would you be willing to consider evidence that came in after the book was written? If so, would you be willing to accept evidence from professional biochemists, geneticists, geologists, etc? What exactly do you mean when you say a "lack of evidence?" What kind of evidence would be compelling to you? Would you be willing to consider opinions of professional geologists on your last point about how fast rock erodes?
