Prophecies prove both that He exist, and that He wrote the Bible. Have any statistician work up the odds of an exiled people maintaining a national identity, not to mention a language, for even ONE thousand years, let alone almost two.. It\'s never happened before, and it never will again. Exiled people eventually (usually within just a few generations) just get absorbed into their host cultures. But HaShem chose the Jews as the keepers of the Word, and they couldn\'t do that if they went to Russia and became simply Russians, went to England and simply became English, etc.. So for two thousand years, the Jews maintained a sense of nationality aside from their host countries, and continued teaching their children the language of Tanakh. Without this, Israel could not have been regathered.
