Have you actually studied it in depth beyond the few verses that atheists usually pick out as shockers? It's about chosenites, yes, milk-drinking, chariot-riding, giant-slaying, colonising ranchers/ shepherds. It's not written to be a fable to teach individual moral lessons, but a record, so it contains stuff that is not uplifting but instead shameful. The only people that fit the Exodus story in Egypt are the "Hyksos", which doesn't at all match up with what Jews claim, or their timeline, so they deny it outright. Would you say that the Phoenicians are Jews/ Palestinians? That means they colonised parts of Europe's coastlines and set up trade routes across the Mediterranean, and also gave the Greeks/ Romans their Alphabet.
