Let's say I was a person who had never heard of any types of religion, or was an alien from space, or some such situation where I had no prior knowledge about Greek and Christian mythology. I am given two books such as Ovid's Metamorphoses and the Bible. What reason is there for me to believe that one is a fictional story about mystical Gods and the creation of the universe that was written by man thousands of years ago, and the other is the Factual Word from The One True God about the creation of the universe written by men thousands of years ago? How would you convince me to base my life on the teachings of one, and dismiss the other as merely a story?
