As for the second thing you said, it was very silly. Jesus is claimed to have lived +/- 30 years from year 0. Alexander the great crucified 2000 people in tyre in 300's BC. Herodotus, who DIED in 425 BC told us about persian crucifixion. Now, and if this offends you excuse me, if you are honestly saying that people had made mentions and allusions of jesus dying on a tree or being crucified 400 years BEFORE Herodotus, than you're insane. As nice as you think it would be, there is NOTHING from before 800 BC that mentions Jesus. NOTHING. I can make allusions and claim mentions about anything I want, but that doesn't make that true. Furthermore, there is NOTHING from 500 BC talking about jesus. And there is NOTHING from before 100 BC mentioning Jesus.
You mean besides the Old Testament prophecies that were written between 1000 BC-600 BC? You can call some of them off and say, "well, that's so vague, that could mean anything," and then there are others where it is so obvious that the passage in question refers to Jesus. Just on the top of my head, Psalm 22, particularly the first half, is very similar to the New Testament accounts of Jesus' death by crucifixion. Even if you don't believe the Bible is divinely-inspired or what have you, you can't deny the fact that those prophecies are much older than Jesus.
as a matter of fact, Josephus, a jewish historian who was born at 37 AD and wrote most of what we know about life in Canaan at the time makes not a single mention of jesus, the great wizard, magician, healer or what have you. Keep in mind jesus is claimed to have only died 7 years prior to that. forgot him that quickly?

Josephus does mention Jesus in a short passage in passing (he says something like, "there was a man named Jesus, brother of James, who was called the Christ"), however, other passages relating to Jesus have been assumed to have been tampered with. In addition, both Tacitus - a Roman historian who documented the rules of the early Caesars - and Lucian - a playwright and satricist who mentioned Christians and their gullibility in one of his plays - mention Jesus, the latter not in a kindly fashion. Neither of them are contemporaries, but at the same time, Tacticus was a reliable historian. You can't just reject his small segment on Jesus because its supposedly hearsay.
None of the historians who lived at the time of Jesus documented him, in my opinion, because he was simply considered a rabble-rouser who occasionally caused trouble, and was eventually executed by the Romans and Jewish leaders. His influence did not become widespread until after his death. Keep in mind, Judea would have been considered a 'backwater' province back then; most historians would most likely focus on the events happening in Italy, specifically Rome.
