funkyderek notes,
Nobody writing in the first century seems to have heard of Jesus at all.
That's exactly right. Furthermore, the gospel writers alleged that extraordinary events surrounding the life of Jesus occurred, but nobody but the writers knew about them. Consider, for example, the story of the slaughter of the innocent children:
The wise men found Jesus but didn't return to tell Herod, who became "exceeding wroth, and sent forth, and slew all the children that were in Bethlehem, and in all the coasts (Greek horios: districts) thereof, from two years old and under." (Matthew 2:16)The story of the murderous Herod is found only in the gospel according to Matthew; nowhere else in the Bible is it mentioned, and no Jewish or Roman historian of that time says a word about this sensational event. The Roman historian Cornelius Tacitus (110 AD), who went out of his way to record every misdeed of despots and tyrants, was completely silent. Silent also was Josephus (40 AD), the Jewish historian who provided a detailed account of all the lesser evil-doings of Herod up to the end of his life; not a word did he write about Herod's massacre of the innocent children.
Apologists can look until they’re blind, but they will find not a single account of this amazing event outside the writings of Matthew; that’s probably because Matthew either was repeating an urban myth of that time, or made this story up himself.
And what about the miraculous feedings on the shore of the Sea of Galilee? Jesus was alleged to have fed to satisfaction 5,000 people (Mark 6:32-42), with food left over, with only a handful of bread and fish, then days later fed another 4,000 the same way (Mark 8:1-9). Surely thousands of the participants in these "miracle" feedings would have made known their experiences to journalists and historians of that time, and passed along first-person accounts down through the generations. However, there exists not a single historical account of these events outside of the gospels. The most likely reason for this complete lack of evidence of the events is that they never occurred in the first place; they’re just as fictional as the “Jesus” Mark, Matthew, and Luke wrote about.
And why did nobody but Matthew know about all of those gruesome revived corpses chatting up the folks in Jerusalem?
And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many." (Matthew 27:45-53)
