There was nothing magical about Jesus and Jesus had no power, everything he did was done through faith in the Father, aka God, working through him. And he's hardly the only one who performed miracles. The disciplines cured people and raised the dead as well (but didn't make any free wine, fish or bread that we know of). Again not by any power of their own, they were ordinary people.
Therefore cloning Jesus would prove nothing except He was a son of Man which we know. And if he performed some 'miracles' people nowadays would just look for some scientific explanation for how he did it, or just lump it in with all the other 'unexplained' stuff that happens like faith healings that still happen today.
