Well put, Squidfetish!
I have to honest here, on a scale of religious belief (0 being hardcore atheism and 10 being hardcore religiosity) I'm at about a -11.
I'm not actually sure there is or ever will be any "evidence" or well reasoned argument that can ever convince me of a god's existence. I even used to say that if a god parted a mountain and commanded me to believe, I would believe instantly and without question. Now, after rethinking it all, I still wouldn't believe.
Every single one of us is cursed by the fact that our brains are not, in any sense of the word, objective. We see patterns where non should exist (Like in toast, for example). We misconstrue memories and events of our lives instead of storing what actually happened (Although we are certain, in our minds, that it actually
did happen that way.) All of our senses are shaped, stretched and interpreted by an organ which defines its own unique reality and not one in which any two people can agree on.
Take the "parting of the mountain by a god" example. I can evaluate the situation as such:
What are the odds that some alien creature (That evolved in our universe) is just fucking with my brain and claiming to be something that it is not by using an understanding of our culture, my own mind and advanced technology? Very low, but possible.
What are the odds of me being nothing more than a computer simulation with someone behind the screen fucking with my sensory input? Pretty low, but still plausible just based on how far we have come in the last 150 years technology wise.
What are the odds of a single, sentient entity creating countless light years of ever expanding time and space (That happens to reside
outside of the time and space that we think we know exists) and then traveling to Earth to prove to me that it exists? Way, way, way less plausible than something just fucking with me.
Even if an event defies everything we
know to be true about the world in which inhabit, there are always more likely explanations than a god as described by holy books.
So, I guess I am a fundamentalist about my stance on the issue.
