From the physical standpoint, the book is words and confusion. From the spiritual standpoint, it makes sense.
The Bible often speaks in symbols, the language of the subconscious-soul. For example, Eve being taken from Adam's rib/side means that man and woman are two parts of a whole. This is something people don't understand.
The coolest parts in the Bible are the explained differences between the flesh and the spirit, Jesus talking, and angels coming to people's dreams.
