This is all you have to show as a fact that the Bible is true, and Biblegod is real:
Say this:It is a fact that not only is everything in the Bible true but it's a fact that God exists.
When asked as to what evidence you have, here's your evidence:
The use of the word fact doesn't just have one single definition; if one looks up the word they can see that it can mean:An objective consensus on a fundamental reality that has been agreed upon by a substantial number of people. 
Since a great number of people believe that the Bible is true, then it's a fact that it is.
Since a great number of people believe that the god in the Bible is real, then it's a fact that it is real.
Now, some may point out the word "objective". This is the definition you use for that word:agreed upon by all parties present (or nearly all); based on consensually observed facts 
Make sure that when "all parties present" are there, that they are those of a like-mind.
Note the use of "facts" at the end of that definition? See, it's all working out for you. You now have evidence that can't really be disputed based on facts that the Bible and the god in it is not true. Consensus states that it is true, and Biblegod exists. Well, consensus of those that are Christian, of course.
However, it should be noted that if you do this, you're also showing, by consensus, that everything in the Bible is not true, and Biblegod does not exist. Why is that? Because Christians always spout off that they believe based on Faith not evidence -- which they show is their evidence.
