If you'd ever read a book, you'd know that bats weren't classified as mammals until the 18th century when Linnaeus made his taxonomy. Well over 100 years after the Bible was translated into English.<quoted text>
You do not know what people thought 2,000 years ago. And the Bible is not a book about what people thought, you claim it is the word of God. Therefore God is an idiot.
But I'm sure you already knew that.
