Muslims: don't you think that a god who cannot keep his "holy" books safe is not worthy to be worshiped?

They have no proof and the Dead Sea Scrolls prove it hasn't been changed (and also proof that the Bible will never disappear and is protected by God. Yes, there are translations but there are hundreds of translations of the quran too so that a ridiculous argument. As far as 1 in 3 memorizing the quran I doubt that is even true considering most muslims have no idea what the quran says.
