If true, amazing

Associated Press: Group Discovers John the Baptist Cave

If the cave they found is truly the one used by John the Baptist, then suddenly a major part of the Gospel story is now fact according to the non-religious world. It makes it much harder to simply dismiss the Gospel story if a major portion is corroborated by archaeologists.

But how can someone prove any cave was used by a man who lived 2000 years ago and didn't leave any of his own writings and didn't start a movement of his own? If one believes John the Baptist lived, then its easy to see how this cave could have been his base in the desert. If one does not believe John was a real person or the Gospel anything else then a good story, then other explanations will be found.
