Jim: "Faith is believing something you can’t provelike atheism and evolution."
Atheist: "Atheism is the negative response to the positive claim 'There is a God!' from theists. So it's the theists who have the burden of proof. They have to show to a great enough degree of certainty that their God is in fact real! And evolution has been *observed*! Case in point: nylon-eating bacteria!"
Jim (very smugly): "How are you wrong? Let me count the ways! It has been regarded as a self-evident fact for all of human history that God(s) exist, atheism is the exception to the rule! So it's *atheists* who have the burden of proof. They have to prove *beyond all possible doubt* that there is not now, nor has there ever been, a God! And it has never happened that a zoo monkey has turned into a human, so evolution has NOT been observed!!"
