Let me ask you a question, and please answer as honestly as possible:
What piece of evidence, if found, would you consider convincing (concerning evolutionary theory)?
Piece of evidence? Setting the expectation a bit low aren't we? How much evidence does it take to put a man to death in the electric chair? Enough to spell out the case beyond a shadow of a doubt that he did it, right. And that's what I think rises to the level required.
What would it take for you to believe God and believe in God. Seems a fair question. I think similar proof would be required. Given the millions of animals on the face of the planet, surely you would be able to find one living animal group that is observably in transition. It doesn't take millions of years to happen any more than it takes mere seconds. Fact is you don't know how much time it takes because it's never been witnessed. So, rather than using time as an excuse, go get us a species of animal that is incontravertably as a group in transition - growing wings, an extra set of legs, a speices of fish growing arms and legs.. Should be a pretty easy task. Given the odds and the billions of living critters out there, it should be observable somewhere on this planet.
I know, I know. Too obvious, huh. And you've built that into your theory to explain away why evolution isn't being seen now. Spare us the handwringing and show it to us in progress. Unlike God who doesn't just walk around down here to directly observe, you have an advantage of vast populations of animals and fish to draw from in the here and now. The only thing left is excuses. No excuses. Put up or shut up.
