I dunno. How many posts have you made in which you made definitive statements as to what is and isn't in the Bible?
EDIT: No actually its fine, its a debate and a discussion ... it is always best to be corrected and learn, no matter who from! (and have a little humility for once as a reminder ... It was meant to be ... in order to be a better Christian)
There isn't anything wrong with learning when corrected but you don't seem to do that unless a direct Biblical quotation is shown to you. Also, since you can't state everything you believe, a surer method of learning would be to go directly to the source, read it, and educate yourself from that.
Apparently, your knowledge of the real world and reason led you to believe that a "fire-breathing fairy tale dragon" couldn't possibly exist so you assumed that one couldn't be in the Bible. Now that you know that one is in the Bible, do you now reject your knowledge of the real world and reason to accept that there were/are such beasties? Or do you retain your reason and assume that the Bible says much that can't be true?
