Isn't an 'all or nothing' attitude rather simplistic? Of course some things are that easily black and white, but there is no reason to think the Bible is like this. Divine inspiration doesn't mean the Bible has to be the exact words of God. It can mean that the overall meaning and principles are what are inspired, but the way in which those principles are expressed are confined to the culture they were written in.
Personally, if accepting the Bible as a divinely inspired book is sophisticated, I'd rather be a simpleton. I think that religions need to make sense and pass basic tests of reason. If they don't have to make sense, then why wouldn't you believe that I'm a deity who created the universe 5 minutes ago with all of your memories included?
There is an argument called the "argument from locality" or something that goes like this:
If a deity really wanted to make its existence known to humans, it would reveal itself consistently throughout history including in the present day. It would not make its presence known explicitly through miracles only to a particular ethnic group or to people of a particular time. Rather, it would reveal itself to all people all over the world all the time. Missionaries would travel to remote jungle locations only to discover that the natives have the exact same deity, symbols and doctrines as the missionaries. That would make sense. The idea that God desires humans to know of his existence, yet he requires us in the present day to believe that humans from one particular ethnic group who lived 2 to 4 thousand years ago are telling us the truth is illogical.
For example, people alive in Jesus' day, who saw the miracles, crucifixion, resurrection, ascension etc. didn't have to have any faith that other people were telling the truth. We on the other hand, have to believe that ancient biblical authors were telling the truth. Due to all the miracles and stories involving God, it's not the same as asking us to simply believe in some plausible, historical story. It's asking us to believe that ancient people's accounts of supernatural events are true. It does not make sense. (If a Wookie lives on Endor you must acquit.)
I agree with you. The Bible likely talks of a solid firmament above the earth. I have used this in a thread against creationism before. I don't have any problem with this because the main point of the Bible isn't to be a science book. The main points seem to be about meaning, the correct way to live and our relationship to God. These points are made through the past culture though.
There's no good reason why God doesn't show himself today or at least have prophets on the planet in 2011 who can perform miracles for the scientific community so that we all have proof of God's existence, if he really wants humans to know that he exists as the Bible and Christians claim. If he let his presence be known today through miracles, it would only be a matter of do we as humans choose to reject God, or do we choose to worship him. As it is, the issue is do we or do we not trust that ancient people were telling the truth.
