Greetings,
I didn't answer the poll as none of the options apply to me. I would guess that many atheists would say the same thing - a 'none of the above' option would win, I'm sure.
I don't believe in any god or gods. Zeus and Thor, we can probably all agree, are man-made. These and thousands of others show that humans have a propensity for inventing deities. Ontologically, the god of the Abrahamic faiths is, in my view, no different from any of these. I just believe in one god fewer than a Christian, Muslim or Jew.
The reasons why I don't believe are many and various, and you've probably heard them many times before: no evidence, the problem of evil, the all-too-human content of religious scriptures, Occam's razor, "who designed the designer?" and so on. If you don't subscribe to these these arguments, that's obviously fair enough, but I do.
Most of these atheist arguments have existed for many years, yet people carry on believing, so I won't lose any sleep over it. I remain fascinated, though, by finding out why people believe what they do. I often find that people with the most sincere belief in a religion believe in the way they do for reasons that can't properly be expressed in objective language.
God is only real for me in a similar way to the way Hamlet, Odysseus or Sherlock Holmes are real. It's my view that God (with a capital 'G') is nothing more and nothing less than the most influential fictional character in world literature.
Peace
