OK, I'll repeat myself. Why are you so dumb?
Here's what I mean: do you suppose you are the first person to have discovered all that stuff in scripture? If lots of people smarter than you have been reading these books for thousands of years (assuming you allow the possibility that there exist people who have ever been smarter than you) and have somehow concluded that scripture is not all garbage, does it occur to you that they may have something useful to say about the subject? Or are you so taken with your own amazing smarts that you don't need to pause to consider that the civilization that thinks these works are worthwhile are really worthwhile?
