What i consider as historical proof are things that have been independantly documented by many..
Ill tell you why jesus is questionable.. the only proof of him is the bible..
lets pretend now. there is a guy in the islam nations causing a huge stirr messing with their religion, gaining a huge amount of followers and converts. This stuff would be documented. Letters from one person to another going dude did u see this guy hes making the place go crazy. THERE IS NOT ONE LETTER
ur saying hey it was a long time ago stuff from bak then.. well its prolly been destroyed over time. WE HAVE letters of people talking about low military officials. Now what is more important Jesus or a low military official.
Im not saying the bible isnt true, im just saying its not good historical evidence of.. a group of people meeting to write. Plus if you look at previous religions [ones that date to well over christs birth i believe around 2k bc] the same things that happened to jesus happened to their prophet/savior whatever u call jesus. he was killed then resurrected etc there are lots of religions with that story
look at this 12 disciples, 12 members of the olypic council, 12 main members of norse gods it goes on
DONT GET ME WRONG jesus is a great inspiration.. but that doesnt meean he existed. look what the bible teaches so many, why does it matter if its based on history. it doesnt need to be.
