The difference between Jesus and the others you named is that Jesus ascended by His own power and authority. The others were taken up into heaven. Did you see the link I gave no_outcome above?
No, I haven't checked out the link yet. It is not a point of critical concern to me right now. Please don't think that I equate Jesus as somehow equal with Enoch, Elijah, or anyone else. My point was, the wages of sin is death. It follows that anyone without sin is not required to die.
