I said, "No statement found in the Bible has never been proven to be false."
And I will say again, "If you think one has been successfully refuted, you are quite mistaken."
1. The Bible never makes a claim that a snake talked. I assume you are referring to chapter 3 of Genesis which says,
"וְהַנָּחָשׁ֙ הָיָ֣ה עָר֔וּם מִכֹּל֙ חַיַּ֣ת הַשָּׂדֶ֔ה אֲשֶׁ֥ר עָשָׂ֖ה יְהוָ֣ה אֱלֹהִ֑ים וַיֹּ֙אמֶר֙ אֶל־הָ֣אִשָּׁ֔ה אַ֚ף כִּֽי־אָמַ֣ר אֱלֹהִ֔ים לֹ֣א תֹֽאכְל֔וּ מִכֹּ֖ל עֵ֥ץ הַגָּֽן׃"
Now I'm not a genius or anything like that, but I don't see the word snake anywhere in this sentence.
In fact the word is translated into English as serpent. While a snake can be a serpent. It is not true that all serpents are snakes. Only a snake would make such a claim.
2. The Bible was written before today's modern definitions. The Bible does not contain a statement ever calling a bat a modern day bird. It doesn't even call a bat a bird at all. I assume you are referring to Leviticus 11 verse 13 and verse 19 which say,
verse 13
וְאֶת־אֵ֙לֶּה֙ תְּשַׁקְּצ֣וּ מִן־הָעֹ֔וף לֹ֥א יֵאָכְל֖וּ שֶׁ֣קֶץ הֵ֑ם אֶת־הַנֶּ֙שֶׁר֙ וְאֶת־הַפֶּ֔רֶס וְאֵ֖ת הָעָזְנִיָּֽה׃
verse 19
וְאֵת֙ הַחֲסִידָ֔ה הָאֲנָפָ֖ה לְמִינָ֑הּ וְאֶת־הַדּוּכִיפַ֖ת וְאֶת־הָעֲטַלֵּֽף׃
Now, from verse 13 we have the word הָע֔וֹף which when transliterated into English reads "hā-ō-wp̄," "which comes from a root word which means to cover or to fly." The category of 'owph includes birds, bats, and certain insects."
Does the Bible call a bat a bird?
I'm not sure you know this, but bats can fly. Bats may not be birds as birds are defined today, but bats are certainly הָע֔וֹף.
The writer of Leviticus did not approve of the use of the English word bird as a substitution for what he actually wrote. Nor would He.
I'm not going to prove you wrong on every count. Hopefully you are wise enough to see where this is going. If not, too bad.
