In my opinion, chakka, you have your mind so made up that you are willing, as are some skeptics, to hold the evidence for Christianity to a totally different standard than the standards for reliability used for almost all other historical events.
You know, for example, that Josephus is generally assessed a credible historian. But, you are willing to denigrate only those portions relating to the Christ. You've expressed the same view of Pliny, Seutonius, et al. Your view is that the Gospels are not authored by those so named, but do give slight credence to Paul, who, ironically, names those individuals and, obviously knows them well (other than Matthew). Your consistency is as fluid as your reasoning, in my opinion.
Scholar after scholar, (skeptic and believer) use certain rules and guidelines in determining the validity of ancient documents. You certainly know that you can Google credible scholastic tomes authored by Phd.'s that hold the Gospels to the same standards as, say Tacitus (The Annals or The Histories). Yet, again you most certainly know, that the earliest copy of Tacitus' The Annals occurs 950 years after the date of the original. Even copies of Caesar's Gallic War", accepted by almost all historians as reasonably accurate, did not occur until nearly 1,000 years followng the autographs. Tacitus has two copies extant, while Caesar has only ten (10!).
In England, one of the earliest copies of the Gospels exists that is just 114 years after the original. There exists fragments that are only 25 years after the autographs, Now, with further study of the Dead Sea Scrolls, there's a good possibility that fragments of Mark and Matthew are included that date to just 5 years after the original..
