Plenty of the references in the Bible to Christ are quite plainly fabricated from thin air, not the least of which being at least one conversation with God out in the wilderness with no other person in sight and one instance of Jesus's direct conversation with Satan, again in the wilderness and not another man in sight.
Furthermore, many of the gospels flatly contradict each other about Jesus, and then of course we have the account of Christ's childhood; why would anyone have taken notice of Christ before he did anything worth noticing?
If i remember correctly, the only writings we have from someone who was actually alive at the time are those from Josephus. From these writings we can confirm that there probably was a rabbi during the 1st century CE called Jesus, and he was probably pretty radical in his beliefs, but we can't actually attribute any of his sayings directly too him due to translation issues with ancient languages.
Josephus's writings also agree with the roman historical records and military commentaries, so there's a good chance a rabbi named Jesus did live at some point around the time given. The liklihood of him being anything like what is described in the Bible though is remote at best, past simple things like radical teachings and causing disquiet in Jerusalem here and there.
