IMO you can't suggest that the bible doesn't have to be interpreted literally and still maintain that it is the word of god. If you do then it all becomes quite meaningless. In any case, if you are suggesting that then you are in a small minority I believe and not only that, you are grasping at straws.
Do you believe that there are only two choices, that the Bible is literal and historically factual, or that there is no god?
Those are not opposing choices. I believe that the bible must either be interpreted as literal or it must be discarded as a work of fiction and fantasy. By definition it suits that description IMO because anyone living in a modern world can't interpret the bible as literal. I believe that there is no god but to prove a negative is quite impossible. I may however believe that there is a celestial teapot orbiting the sun just outside the earth's orbit. Neither can you prove that it doesn't exist but it's quite reasonable to suspect that it doesn't.
God did leave evidence of his existence in his creation, not in the ancient writings of Man, but, that still doesn't prove the existence of god.
No, god didn't leave any evidence of any kind in any socalled creation. Science has provided with perfectly plausible explanations which support Darwinian theory which tells us that life evolved from most probably one event in the beginning from a very primitive form of life.
Disbelief in the literal interpretation of the Bible doesn't disprove god, either.
Disbelief in a literal translation of the bible leaves you with nothing on which to base your superstitious beliefs. You would be much better off trying to reconcile what the bible says with the real world as many actually do. If you don't then you are doing nothing more than making excuses for the errors contained in your bible.
As of just recently in the last couple of weeks there has been new evidence discovered which could maintain that the bible has been found to be factually incorrect and in error. If that is the case then the bible can no longer be considered the word of god for obvious reasons. If the Christians handle this new evidence in a creative manner then it could be cause for a rewriting of the bible which would then be able to reconcile it's words with modern knowledge. I would suggest that christians don't lose the opportunity.
