Why is it that so many  people believe Moses and Elijah are the two witnesses?  The Law (Moses) and the Prophets (Elijah)?
 
However, if it is appointed unto man once to die, Moses has already died.  The other bible rapture belongs to Enoch.  Enoch and Elijah are the two that never died, ergo, seems like those two are the most likely candidates.  Just a thought.
