Do you have peanut butter? Then there's no evolution! http://www.youtube.com/watch?v=FZFG5PKw504

I honestly don't know what to say. If no human being has ever seen something happen, then we can never definitively prove it happened, we can only guess.
NOW, we do have evidence. Evidence from selective breeding shows that genetic selection conducted by humans, can create new animals -- there are hundreds of breeds of dogs, and most domestic livestock have been modified through selective breeding to be very different from their ancestors.
Does this show that evolution has occurred? No. What it does do, is show that evolution is
plausible.
There is ample evidence of evolution regardless of how well carbon-dating works. We know this: Fossils pre-date both living things and the recently deceased. We know this because fossils are dead, and recently deceased animals do not immediately turn into fossils.
Ok? Agreed?
So, if we find a fossil of a dinosaur with feathers, we can perhaps ask ourselves, "could birds be descended from dinosaurs?" Further evidence of the dinosaur bones, showing similar structure to avian species of today may further confirm that suspicion...
Hell, we'ver even
created whole new species through selective breeding (not that it proves that it happens in nature...).
You'd make a bad prosecutor if you don't believe in evolution though, because not believing in evolution ultimately amounts to a denial of genetics. A denial of genetics would make it hard for you to uphold DNA evidence in court, wouldn't it.
