I don't "believe in it"......it is a default position.
I think this is the very heart of the issue for me. Humans have always used the supernatural as the default explanation for anything that seems inexplicable at the time. Like I said before, throughout human history, supernatural explanations have continually given way to scientific explanations, but never the other way around. Therefore, I do not accept the supernatural as the default position. The default position, in the absence of evidence, should be "We don't know". We don't know the origin of the universe. We don't know how life began. We don't know a lot of things. We are only human after all. I have a hard time seeing how my default position is arrogant, or contains hubris. I think it is the ultimate act of humility to admit what you don't know.
In contrast, the default position that you and others seem to be advocating is one or more of the following:
-My god is the only god and I am going to believe in him no matter what.
-My god is the only god and I am going to kill you because the culture that I was born into believes in a different god than the culture that you were born into.
-I don't know whether god exists, but my parents/priest/reverend/etc. told me that he does, so I believe it too.
-There is a really old book that says god exists so I believe he exists.
-I have strong emotions when I think about god, so I believe he exists.
-I am uncomfortable with not knowing how the universe began, therefore I choose to believe that there is a god.
-I don't know whether there is a god, but according to what other people who came before me have said, there might be, therefore, I am going to devote resources (time, money) to an organization that seeks to propogate and spread this belief even though this belief has brought pain and destruction to the world for thousands of years.
I believe that each of these positions contains quite a bit of arrogance. I think it takes quite a high opionion of oneself to take any of the above positions.
