There exist a very small number of references to an historical figure who's often agreed to be the same person as the Christ described in the Bible, but none of these do much more than attest to this person's existence. This is a topic that comes up fairly frequently here, however, and, while there is always more to say, this earlier response by u/talondearg goes into some detail about what we can and cannot know about the historical Jesus. You might like to review it while you wait for fresh replies to your question.
