Well if Jesus did ascend in the literal sense;  from where on a global planet is true 'up'.  Do those who rise from the dead need to breathe.  It is also written that Jesus ate with disciples after the resurrection.  Are we to believe that all our bodies will rise from the dead and need nourishment.  How far will Jesus ascend before He runs out of oxygen...if He needed food, He must also need to breathe.  That is why much of the Gospels are metaphorical and not reality.  To accept myths and superstition over modern science and what we now know to be true is the 'folly of faith'.
