Would confirmation of the "Biblical Exodus" add any support for God

Let me see if I have this whole argument right in my head.Which of the following statements are supportable?1) If God exists, the collection of books known as the Bible are literally true.2) God exists (supportable or not?)3) The events in the modern day translations of the books of the Bible are unsupportable. (True or False) Or maybe unknown?The reason I would say that some of the events are supportable is based only on stories reporting eyewitness testimony from that era. My conclusion, that the Bible is unsupportable and that God is unsupportable does not interfere with my personal beliefs.
