All the historical evidence for Jesus in one room
Is something true because the majority says that it is true or because it is true?
This is pseudo-skeptical nonsense. These scholars have done the research and digging into sources and have the evidence that Jesus, the man, existed in the time that the gospels Bible describes. Until you have evidence that either disproves his existence or disproves all the historical records, this is contrarian nonsense with no basis in how historical research is done.
