I'm a bit taken aback that you actually considered that a credible reply. Haldane's answer was more of an arbitrary “I can quit whenever I want to” than a legitimate object of inquiry.
What an artful ruse you've concocted for yourself. Not only have you saved yourself the trouble of doing any real work and actually finding the pre-cambrian rabbit first, you've insulated yourself from any of the other multiple falsifications that would disprove evolution. If I had said show me that selection and/or environmental variables don't favor the reproductive success of better adapted specimens, you'd just say, "A specimen better adapted from non-environmental variables would be incorporated into evolutionary thought even easier than the lack of transitionals."
Creationism's survival as a modern day cargo cult/multi-level marketing scheme owes itself to this kind of ingenuity. Who would've thought that repackaging George McCready Price for modern consumption would be so successful in the modern evangelical community? Even the Catholic Church gave up 60 years ago, but here you are in the 21st century regurgitating flood geology talking points.
You earn no points for scientific understanding, but score big for tenacity and creativity.
