Your "Roman historian Tacitus" was born more than two generations AFTER the death of the supposed "Jesus" and could only have written things that were already tainted by belief and wishful thinking of believers!
Also your "Jewish historian Flavius Josephus" was born one and a half generations AFTER the death of the supposed "Jesus" and could only have written things that were already tainted by belief and wishful thinking of believers!
Why don't you use actual history?
