Circular reasoning. Understand that you cannot use anything in the bible to prove anything about the bible. It is the most common fallacy used by religious people.
Leviticus 11:13-23 13"'These are the birds you are to regard as unclean and not eat because they are unclean: the eagle, the vulture, the black vulture, 14the red kite, any kind of black kite, 15any kind of raven, 16the horned owl, the screech owl, the gull, any kind of hawk, 17the little owl, the cormorant, the great owl, 18the white owl, the desert owl, the osprey, 19the stork, any kind of heron, the hoopoe and the bat.
That bible verse, a quote from god, lists "BATS" on a list of birds we should not eat. We know for a fact that bats are mammals, they are not birds. The bible is wrong.
