gospel of barnabas is not accurate

[Sajih]

It is worth noting Eric that over 98 per cent of the evidence which you accuse of being false actually came out of the bible and not out of the Qoran or Gospel of Barnabas . And I hate to disappoint you but I was a former Catholic something that I clearly expressed in the beginning of the presentation . The question that I put to you without any intent to make you feel uncomfortable is

If you do not accept the Gospel of Barnabas NOR THE QORAN NOR THE TRUTH THAT IS IN THE BIBLE; Then what book may I politely ask do you accept?
Plz explain!
