I know this will not convince anyone, but ....
Almost every historian accepts as fact that the Punic Wars were historical events.
Why? Our knowledge of the Punic Wars (and that they even took place) is based on ten, and only ten, supporting historical documents.
The New Testament is supported by over 24,000 historical documents outside of the Bible.
For atheists, this argument means nothing. For believers, it also means nothing.
For us believers, we base our beliefs on our faith in Jesus Christ and His influence in our lives, not on historical documents.
