Gosh, one does have to be patient. Of course there were references to Jesus well after he was supposed to have lived. The early Christian proselytisers were scrawling their tendentious stuff all over the place and that was going to be picked up in subsequent centuries by all and sundry. Robin Hood didn't exist but that doesn't stop people getting all romanticated about him as the centuries unroll. The point is that no-one outside those early Christian circles ever gave Jesus even the teensiest mention. Either the thousands of contemporary writers were all part of a big conspiracy, or else the case for the existence of Jesus is thereby seriously weakened. Take your pick.
