> Sure, and Louis Pasteur was a crank for claiming that invisible micro-organisms were causing infection and disease. Your absence of perception does not mean the evidence is absent.
I don't understand your example. Louis Pasteur determined germ theory by observations of natural phenomena - he observed evidence, experimented, and found an explanation for said evidence. In this case I'd need to see direct evidence of a purpose and a means by which I could observe or experiment with said purpose.
> The default option is faith/belief.
You need to provide some reasoning behind that. And which faith? Some belief? Some god? Do you believe in UFOs, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster, and the theory of Atlantis?
> You don't have "strong evidence" each day that the sky will be the same color, the sun will come up, your dining room chair will still hold your weight, your best friend still loves and cares for you, and that your car will likely start at the crank of the key.
You're not understanding - I'd need to have some form of reason to believe that the sky would change, or that the dining room chair's properties would change. I'm saying that my understanding of the world is based upon observations. I observed the sun comes up every day so I assume that it will tomorrow. Unless something acts on it it will continue to do so I have no reason to not assume that. For it to not come up the next day without any reason to would in fact be a supernatural phenomena.
