Jan,
You wrote: Jesus allegedly fed what corresponded to the population of an entire city miraculously (twice!).
However, few among them may have been aware of the miraculous nature of their meal. For Jesus gave the loaves and fishes He had multiplied "to his disciples and they in turn to the people." (Matt. 15:36) Those who did understand what had just taken place and told such a story to others would hardly have been taken seriously by secular historians.
You wrote: Herod did a crime so extreme it is amazing if it was not recorded (e.g. by Josephus, who carefully listed many lesser crimes by Herod).
You are speaking, I presume of Herod's killing of John the baptist. As the Bible tells us, "Herod was afraid of the people because they considered John a prophet." (Matt. 14:5) That being the case, it is very likely that Herod ordered that his killing of John not be publicized. His order may have been quite successful in keeping his actions from the public at large.
You wrote: Not to mention all those "saints" suddenly resurrected and walking around in Jerusalem talking to people.
You, of course, refer to Matt. 27:52,53. As you probably know, the exact meaning of this passage is disputed. Some say that the resurrection there spoken of was a heavenly one and "the holy city" into which the resurrected ones entered was "Jerusalem above." Others say that this passage only speaks of an earthquake which rocked a grave yard. However, I believe the popular interpretation which you allude to is correct. I just think that, then as now, when ridiculous sounding claims seldom get repeated by "respectable" historians.
So far as your other attacks against the Bible's credibility and your allegations that it is filled with contradictions, I believe I could offer reasonable explanations for every one of your alleged "contradictions." But what would be the point? Even if you were convinced that the Bible contains no contradictions, as you have said, you are not going to accept extraordinary claims without extraordinary evidence of their accuracy. And as I have said, I believe that if you are willing to believe God and serve Him He will eventually provide you with all the evidence you need to put your Faith in Him.
