This is interesting as archaeology is always interesting. I’m surprised at the attempt to make historical claims based solely on physical structures extant in the first century CE. Dealing with Palestinian history during Roman rule is a problem only for those attempting to unsupported claims.
The creation of the what would become Christianity was tied to the anti Roman movements and various “prophets” as political instigators. The primary historical conjecture is a combination of oral traditions surrounding these political leaders and their actions during roughly two hundred years. The documents that became identified as the gospels were not compiled until the second century very loosely based on written records from the oral traditions.
While there are no Roman records of anything prior to 60 CE there are the letters of Saul of Tarsus who seems to have been the primary creator of the Greek style mystery cult that became Christianity. I’ve long been interested in that person’s real intent. It would appear that he had access to oral traditions as well as living members of families that would have known the origins of the stories. The fact that Saul specifically blocked any detail on this allowing a fully mythical form as the basis of a an Hellenized Hebrew cult is historically disappointing but illustrative of the belief systems of that time.
That the stories collected described a range of places and buildings is not surprising but doesn’t prove anything beyond the existence of those places and buildings.
