No there are not - no first hand accounts, nor by anyone else - see AI. aka no proof.
E.g. the Pilates letters send to Tiberius (Jesus trial) are written by another person - so no first hand account!!!
but factually a forgery.
And factual history is NOT based on a single word/story source and "sold" as a "historic account" - but several independent sources based onto several stories, and material/archeological proof, e.g. Egyptian papyrus texts, that are found as well on a granite Steele or sarcophagus - become "proof" towards a factual historic account.
That is why the words of the "Jewish" bible have no historic relevance - since no other historical accounts from e.g the Egyptians, Hittites, Philistines, Assyrians, etc. ever mentioned a state of Israel, nor a King David nor a King Solomon presiding over a State called Israel - even the rulers names and buildings are in dispute.
Only the OT, written/composed entirely by Jews/Hebrews, and constantly "amended" through centuries mentions/claims all this.
Tacitus records that the Roman populace during Nero, called "them" Chrestiani, a term associated with a "mischievous superstition" or "deadly superstition" - it is this Latin description term that around 200 B.C. led to the term Christian. However Chrestiani has nothing to do with "Christ" thus becoming Christian. But simply an invention by the later Roman Catholic Church.
But anyway - wrong thread - and wouldn't make sense to discuss such a topic with a "believer".
