"Then would you be so kind as to do so? At the moment your argument seems to consist of "This is true because I, Steve Shaw, say so." You aren't in the classroom now. I have presented my case; kindly present yours."

Nonsense. The sense in which I say that evolution is true is the same sense in which I say that there's an apple tree in my garden (there is - come and have a look. If you don't believe me, crunch one of my apples come September and you'll be convinced, though it shouldn't really take even that). Explaining why it's an apple tree and not a cherry tree, how and why it bursts into leaf in May, why the blossom is so beautiful yet functional, how the receptacle swells to surround the true fruit... All that's the science, the human attempt to explain the nature of my apple tree. But the apple tree itself is not science. Science is what people do. No people, no science. The apple tree is there whether there are humans to observe it or not. It doesn't need a classroom dictator to decide whether there's an apple tree in my garden. It doesn't need a classroom dictator (Jeez, I was never that!) to decide whether evolution happens. It just does. Now that's my case - you asked me to present it because you've presented yours. Oddly, I can't seem to see yours anywhere.
