Anything more than that requires faith.
Yes and it is doubtful he was born on december 25th. We ridicule muslims because they worship some kind of moon rock yet christians worships Jesus’s death on the phase of the moon.
Well, the Romans knew of him. He was written as one of the causes of riots in Rome back then.
The Roman historian Suetonius (c. AD 69 – c. AD 122) mentions early Christians and may refer to Jesus Christ in his work Lives of the Twelve Caesars.[1][2][3] One passage in the biography of the Emperor Claudius Divus Claudius 25, refers to agitations in the Roman Jewish community and the expulsion of Jews from Rome by Claudius during his reign (AD 41 to AD 54), which may be the expulsion mentioned in the Acts of the Apostles (18:2). In this context “Chresto” is mentioned. Some scholars see this as a likely reference to Jesus, while others see it as referring to another person living in Rome, of whom we have no information.[4][5][6]
Christians are explicitly mentioned in Suetonius’ biography of the Emperor Nero (Nero 16) as among those punished during Nero’s reign.[7] These punishments are generally dated to around AD 64,[8] the year of the Great Fire of Rome. In this passage Suetonius describes Christianity as excessive religiosity (superstitio) as do his contemporaries, Tacitus and Pliny.[2]
