skyking,
You make some good points, I also consider myself a agnostic-atheist, meaning I am unsure about the existence of any god or gods, while I don't discount the possibility that an intelligent force could exist, I see no evidence for such an intelligence and so I live my life as though there were none. However, even if I were to assume for the sake of argument that an intelligent force created the universe that does not validate any of the modern day religions as you have already pointed out, each individual religion can easily be disproven by showing the mountain of evidence contradicting the so called 'holy books' that are out there in existence.
I am constantly dumb founded by these so called 'bible thumpers' who talk about Jesus as if he is their best friend, this is just sad, even religious people would admit the only source we have on the life of Jesus comes from literature. I'm not saying that falling in love with a fictional character isn't possible, it happens all the time. I've even grown strong attachments to characters in some books I've read and thought about them for days afterwards. But when you spend you whole life obsessed with a fictional character and refuse to even glance at the multiple lines of evidence that suggest Jesus’ character at best has been greatly embellished by the people who wrote about him and at worst a complete fabrication (which is what the strongest evidence supports).
When people come and try and argue that 'you cannot disprove god' the reason no one takes them seriously is because they are not trying to make an impartial statement about some possible unknowable being, they are in fact arguing for a very specific god with very testable claims about who he is and what he has done or can do. Yet these cowards are two afraid to come out and say what they really believe because even they know how idiotic it sounds.
