Question regarding the Hebrew Bible

Hi I have a question regarding the hebrew bible.

So first for context I myself am christian. I am in a friendly discussion with a muslim friend of mine. We are talking about each others belief and the christan bible and the Quran. His argument against the bible was that the Quran told that the bible was corrupted along the way by humans who miswrote sections to fake the message of god. One example beeing the catholics and prothestants not including the name of god anymore. On the other hand the Quran is still the same as the original because it is kept in the original language.

Now the problem with the bible is that is really old by now and its hard to compare it with the orignal scriptures. One chance for that is the dead see scroll, but that’s only partly an insight.

With christanity and the bible beeing based on judaism and the hebrew bible I wanted to ask you, if you keep renewing your bible in hebrew (translations aside) or if you’ve decentralized the language and only have modern translations? If you’re doing word for word copies, could you tell me how accurate modern chrisitan bibles are compared to the hebrew bible and if there are big changes that can’t be minor translation errors?

Also just in advance I don’t mean any disrespect and if I have said something wrong, please correct me. I am really just interested in the topic.

Greetings ^^
