This definitely belongs in the soap box. Oh well.
I've had this discussion so many times in the past, and the only thing I've learned is that the only thing to learn on the topic is the lack of learning to be had. Failing to prove something is not the same as disproving it, so bringing up points like that are useless. The only points I could make on this subject worth anything to anyone involve quantum physics and consciousness. It's really not something I feel like explaining, though. Maybe someone else, probably more informed on the unpredictability of electron clouds, the nature of consciousness in quantum mechanics and the evidence for consciousness being separate from the brain, could do this instead. I am but a lowly former arts student, and unfit to wield such grand tools as science.
