Actually, let's treat the Bible, for the sake of validating the event of the Resurection, as one of several historical sources.
Take all of the rest of the Bible and shelve it for the moment, and concentrate on one, happened on earth, event.
You have political/religious revolution fermenting in occupied Jerusalem. The Jewish authorities kill off the perceived leader (the events at the trial are trivial in comparison...but relevant) with Roman passive approval, the said leader's followers claim that the body's missing three days after said leader was put to death. Note: the tomb was guarded by Roman Professional solders, not Jews. It would have been in the authorities best interest to produce the body and squelch the movement right then and there. Again, per the bible, "thousands" of people were converting to Christianity at that point, and the Sanhedrin and other Jewish authorities were appealing directly to the Roman government for the authority to kill off other members of this new movement (ref:Acts 7 and 8, the death of Stephen). The city was dangerously close to a riot.
The authorities, Jewish and Roman, had every motivation to produce the body. They did not.
That fact alone is secularly and logically more powerful than the eyewitness accounts of Jesus being seen/heard after his "death".
The book "Who Moved the Stone" might prove interesting, as it was written by a journalist who set out to disprove the Resurrection (and came to faith as a result of his research).
