Ha. But my atheism (a term I hate, as it's religion defining me, which is scarcely without irony) is also a statement of me saying "I don't really know." All I've done is weighed up the odds of God's existence on a scale of my own construction and found them to be almost unimaginably long. It means that I can completely disregard the influence of any God or talk of afterlife on the way I proceed through life. But that doesn't mean I "know." I don't. Before your offence takes root too much, remember that I did say "It's an uphill struggle for any agnostic to show that their agnosticism isn't just an insurance policy. Which it probably isn't in most cases..."

As for this elusive proof. The real proof of proof will finally be when it gets to be universally accepted. That's the problem, innit. For starters, proving a nagative is notoriously impossible, so the only proof left that may rear its head will be proof that God exists. Heheh - hardly fair! And hardly likely to be universally accepted unless he comes down in a chariot of fire and shows us a load of magic. And even then.... No, agnostics waiting for proof are in for a long wait.
