Ah yes, the standard Christian, backed-into-a-corner-due-to-complete-lack-of-proof response. I've heard it many times. Ok then, even though I think this is an utterly ridiculous and absurd point, I'll bite.
Really then, what we're dealing with here is levels of faith is it not? It takes a minuscule amount of faith to believe in one's own senses. At least in my case being that I'm healthy, not currently taking any medications, using any drugs or consuming any kind of mind altering chemical. I haven't even had a cup of coffee in nearly a decade because of the way it affects my senses.
I can reproduce the same results from my senses every time, without fail. At the age of 32 I have enough trial and error experience using my senses that I feel they are trust worthy. The minute that my senses produce some result completely at odds with the results they have produced in the years prior to that point, I'll try several more times to reproduce the conditions and verify that oddity. If it can be verified, I'll go see a doctor or a psychiatrist and get their opinion. This is a scientific methodology, no?
I have used these senses to form my morality, my idea of right and wrong. For example, I have proven that having children and raising a family, without marrying their mother, is not harmful to myself, their mother, our children or society around me. I know this because using my senses I have deduced that my six and eleven year old children are happy, healthy, well-adjusted children that are doing well in school and in life in general. I have like-wise deduced that their mother, who has been my best friend and companion for twelve years, is also happy, well adjusted and successful in her career and her life. And of course myself, I am also happy, healthy and successful in my life and my career. No harm has come to my family or any one who has come into contact with us as a result of the non-traditional life style we lead, what ever that means.
However, Christians (and followers of other religions) have told us many times that our life-style is immoral and somehow harmful to us, society and the world. They have formed this opinion not due to any kind of proof, because there is none, but because God (a magical, vengeful, jealous, irrational and completely unreasonable man in the sky) tells them that this is so. The existence of this deity and all of his fantastical, magical abilities have never been proven. They have been corroborated by men thousands of years ago, whose existence also cannot be proven and who also claim to have either seen or performed similar supernatural feats, none of which can be reproduced, and one of whom claims to have been the son of this deity by way of immaculate conception, and whom also was said to possess the same or even more fantastic supernatural abilities as this deity and his followers.
Needless to say, belief in this system of morality requires no small amount of faith. And really it's completely irrelevant because if this all could be proven and I had seen this deity with my own eyes, I would not follow him. His rules are not not based off of what is harmful and not harmful to yourself or others. Indeed, many of his followers are and have been extremely harmful, beyond measure, to millions of people all over the world. His rules are to be followed because he says so, period. Such a god is not worthy of my worship.
And George Washington? Well aside from the staggering amount of rational and easily believable evidence available to substantiate his existence, I have never heard it said that he walked on water, turned water into wine or healed the deathly ill with the touch of his hand or the sound of his voice. So again, it takes a very small amount of faith to believe he really existed.
Then there is your argument, which in itself is not only quite extreme, as religious people and their arguments tend to be, but it is ignorant to a staggering degree. You're trying to sway me and everyone else not with proof, but with a complete and total lack of proof. You're trying to establish your lack of proof, as your proof are you not?
I've got an idea. Let's conduct an experiment shall we? Let's change our entire legal system in this country so that it is not proof that is required to win a case, but the total lack of it, and let's see just how well our society functions under that system. Get started on that and let me know how it turns out. I'll be hiding out in a bunker until it's over.
