Wouldn't the tomb of Jesus at the time soon after his death have been a place where worshipers would have gone? And if they didn't go near it for the sake of protecting the tomb, wouldn't followers, especally close to the leadership have know where the tomb was and would it not of been a holy site during the first couple of hundred years?
Was there any evidence of this from the first excuvation of this site?
I think it's an interesting question, but I can offer a parallel example of a tomb whose location has been lost: that of Alexander The Great, the conqueror of most of the known world at that time. He was supposedly buried in Alexandria, presumably in an ornate setting, yet no one knows where it is anymore.
Since none of the gospels were written until at least fifty years after Jesus's death (at least, that's what I've heard on this discussion board) it may be that his fame only spread decades after his death. By that time, his tomb may well have been lost.
A number of individuals express skepticism over this being the tomb of Christ because, they feel it would have been used as evidence of the lack of a resurrection. This presumes two things 1) that Christians at the point of Christ's death felt the Christ resurrected, and secondly that everyone would have known about the Christ family tomb. I think that very soon after the death of Christ, hardly anyone cared or knew about many of these tombs because Rome slaughtered or enslaved most of the inhabitants. These were just unknown graves and tombs to the new inhabitants of the region. Within 100 years, the ideas of resurrection etc. had taken hold and were made into universal Christian dogma, but then no one had any clue as to where the tombs or Christ were, and why look for them if he was resurrected? It not surprising that the growing Christian community, a couple hundred years after he died, had no knowledge of the tomb. look how the Egyptians lost knowledge of hieroglyphics! It is so easy to lose knowledge of things in the present that will be important in the future.
