You could also ask them why the Bible classes rabbits as ruminants (Leviticus 11:6) and bats as birds (Leviticus 11:13-19)

Um...
what? Are you sure that you've thought about this carefully?
How can the Bible classify bats as "birds"? Surely it can only classify bats as
a Hebrew classification, which may sometimes be translated as "birds"? And clearly bats really are part of this Hebrew classification, because otherwise it wouldn't say that!
The modern scientific way of classifying animals isn't the only possible way.

Heck, I've had the same result in church just by asking "What is the value of Pi?", and them showing them how the Bible has it wrong.
As already pointed out, this isn't true at all. In fact, if the implication is that the ancient Jews really thought that pi is exactly 3, it
can't be true. Think about it. It is impossible for a civilization that builds
anything to not figure out that what we call "pi" is somewhere between 3 and 4.
