New Testament - Old doubts...

Last night I was thinking about the New Testament. I was thinking just how outlandish it all is. The idea that God would put on skin, that He would walk around, that He died and that through that our sins are forgiven and we are redeemed from an afterlife spent in hell. I thought about the idea that He was then raised back to life after being for 3 days, I mean, His heart had not beaten for three days, rigamortis had set in, he was , . It is all so unbelievable. What I started thinking about is how there are so many other documents that record events that are just as spectacular or at least similar in their miraculous nature, that we simply discount as frauds. The book of Mormon is one that comes to mind readily.
Here is what I realized. The New Testament is different from all other Manuscripts of this type. It is a set of documents that were all written in the same span of time that the events took place. Let me explain it this way. People live for 60-90 years. Jesus died in the early 30 AD's. The new Testament was all written before or up to about the 80's. This means that a maximum of 40 years had surfaced between the latest writings of the New Testament and the of Jesus. THIS MEANS: that the reports of the New Testament were testable. Individuals could have read the gospel of Matthew, Mark, Luke or John, and simply gone and talked with Nicodemus or Zacchaeus and asked if they had really witnessed Jesus in the manner the gospels record. No other document that I can think of has this same kind of "testability" to it. Joseph Smith wrote about things that had supposedly happened in the past. There is no way we can go and ask someone, did this happen. But early observers of Christianity had this luxury. It is no wonder the church grew by leaps and bounds in those early days. People in Jerusalem had seen all that had happened, they had heard reports and they were asking themselves, "what does this all mean?" Along comes Peter, he does a bit of preaching and explains the "Good News" and THOUSANDS accept Christ. It is no wonder. They accepted because it filled in the blanks for what they had witnessed.
