Lazs,
I'm not saying that 'we can't really know for sure'. You may feel this way, and that is all right, but I am saying that for me I see no evidence of a god at all. The human 'thesis' of dieties, in whatever form, has been disproven beyond doubt for me, and while you leave open the possibility that there could be, I don't.
This is not about belief. This is not about dishonesty. This is about a difference in paradigms and initial assumptions. Some people assume that there is a god, and a lack of proof of a god or gods existance does not disprove absence. I do not begin with this assumption, but look at the issue from the perspective of humans positing that there is, and failing to see any proof whatsoever of the existance of dieties, or higher beings. If someone tried to say there were sphynxs (sp?) flying around, I'd say show me a picture. If they couldn't produce any proof I'd say, well sorry, you've never seen one and neither has anyone else. Let me know if you do come across something, otherwise they don't exist. Since we know that a sphinx is a mythological creation of man, as are dieties, we can KNOW that there is no such thing as a sphinx outside of human imagination.
Simple as that. It takes faith to believe in sphynxs. It is not a matter of believing that there are none. Humanity has been so fractured by religious superstition. It will be a great day for everyone when we can all just get over beliving things without any cause or reason.
