Second, I have not asserted that God does not exist, so your comment is irrelevant.
Third, there is a lot of evidence that the God described in the Bible does not exist.
But there is a lot of evidence that contradicts what the Bible says about God, so I am very confident that no such God exists.
As for the Bible being "true" - that is a meaningless concept because the Bible can be interpreted in a thousand different ways that are mutually contradictory. So the Bible itself cannot be either true or false - it is too ambiguous for that.
