The Holy Bible (66 books)is a reliable collection of historical documents,written by eyewitnesses during the lifetime of eyewitnesses ,who reported on supernatural events that took place to fulfill specific prophecies,and they reported they were divine in nature and not of human origin. You are illogical in saying prove Christianity is true without the Bible. It’s like saying prove 2+2=4 without using numbers! I ask again what evidence would convince you Jesus Christ was God in human form? Maybe an empty tomb?
