"The fact that there are so many versions proves that the Bible has mistakes. Which one is right?"
True, there are many different versions of the Bible. There are versions in Chinese for the Chinese. There are versions in Russian for the Russian people. There are actually thousands of versions of the Bible—some are in modern languages, some in foreign languages, and some are in old English. Few, in the printing age, can claim that they don’t have access to the Scriptures in their own language. However, each translation is based on the original biblical texts. See Psalm 119:105 footnote.
