There you have it boys and girls: You MUST debate evolution within some thin cross-section of time. You may NOT ask how things came into being up TO some apparently randomly-chosen evolutionary beginning point, for "that is not what evolution covers".
Question the evo's with "what came before...." and they act like cats shot with a water pistol, running away while hissing and spitting over their (collective) shoulders, i.e., "what makes you think they can tackle more complex issues?"
They think they have answers, and concerning how nature currently operates perhaps they do, but in my opinion they're to terrified of the answer to even ask themselves the real question.
Here's a start: You evo's do a fine job of describing how evolution works, and you have (what you think are enough) fossils in your little collections, and you've even had some modest success trying to duplicate it in a lab, but not a one of you can tell me WHY evolution exists.
Alas, but instead of grappling with that question, you'll insult my intelligence. Seen it many, many times right here at FR.
What will it be this time? I have a comma out of place or have used a wrong verb form? Perhaps a misspelling will invalidate my opinions, eh?
ah, well: said my piece and I'm movin' on.....If I'm wrong I'll never know it.
