According to the Allexperts web site who answer questions on any topic:
Ask yourself: Could a person who never lived have affected human history so remarkably? The reference work The Historians' History of the World observed: “The historical result of [Jesus'] activities was more momentous, even from a strictly secular standpoint, than the deeds of any other character of history. A new era, recognised by the chief civilisations of the world, dates from his birth.”
Yes, think about it. Even calendars today are based on the year that Jesus was thought to have been born. “Dates before that year are listed as B.C., or before Christ,” explains The World Book Encyclopedia. “Dates after that year are listed as A.D., or anno Domini (in the year of our Lord).”
Critics, nevertheless, point out that all that we really know about Jesus is found in the Bible. No other contemporary records concerning him exist. But is this true?
Although references to Jesus Christ by early secular historians are meager, such references do exist.
Cornelius Tacitus, a respected first-century Roman historian, wrote: “The name [Christian] is derived from Christ, whom the procurator Pontius Pilate had executed in the reign of Tiberius.”
Suetonius and Pliny the Younger, other Roman writers of the time, also referred to Christ.
In addition, Flavius Josephus, a first-century Jewish historian, wrote of James, whom he identified as “the brother of Jesus, who was called Christ.”
"EVIDENCE IN MUSEUM?"
The first-century Jewish historian Josephus referred to the stoning of “James, the brother of Jesus who was called the Christ.” (THE JEWISH ANTIQUITIES, JOSEPHUS, BOOK XX, SEC. 200)
Tacitus, a Roman historian who lived during the latter part of the first century C.E., wrote: “Christus [Latin for “Christ”], from whom the name [Christian] had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus.”—THE COMPLETE WORKS OF TACITUS (NEW YORK, 1942), “THE ANNALS,” BOOK 15, PAR. 44.
With reference to early non-Christian historical references to Jesus, THE NEW ENCYCLOPÆDIA BRITANNICA states: “These independent accounts prove that in ancient times even the opponents of Christianity never doubted the historicity of Jesus "(1976), MACROPÆDIA, VOL. 10, P. 145.
As it did with the Hebrew Scriptures, archaeology has brought to light many interesting artifacts in support of the inspired record contained in the Christian Greek Scriptures.
For instance –
Pontius Pilate Inscription. It was in 1961 that the first archaeological find was made with reference to Pontius Pilate. ( the person who put Jesus to death) This was a stone slab located at Caesarea, which bore in Latin the name of Pontius Pilate
To mention only one, as there are literally hundreds of artifacts relating to everything Jesus said and did. All the people Jesus mentioned, there is proof they existed, all the places he said he visited, there is proof these places did exist, and so on.
To put is simply, if we are to doubt the historicity of Jesus, we must also doubt the historicity of ones like, Alexander the Great and Napoleon, as there is more evidence of Jesus existence than of theirs.
