For what reason would God remove a rib from Adam and use it to create Eve? What a strange idea! Because in Sumerian the word for "rib" and the word for "to revive" is the same. But the guy who was copying it misunderstood it.  Another error, God created the light on the first day and created the sun on the fourth. Apparently the people who wrote the Bible couldn't make the connection between the sun and the light of the day.
