Does every religion have its own Superman?

Argument from Superman: Every religion has its own Superman argument. Moroni, Jesus, Mohammed, Moses, Buddha, even Lao Tzu, are all claimed to have proved their religious teachings supernaturally true by miraculous demonstrations of their power. “Our Superman exists; therefore our God exists.”

This is Richard Carrier's attempt to "destroy" an argument for God. But so many things go awry in his comparison:

i) In the same post, he accusing Christians of cherry-picking the evidence, yet he himself is cherry-picking the evidence. There are founders of notable cults or religious movements who aren't' claimed to have proven their teachings supernaturally true by miraculous demonstrations, viz. Anthroposophy, Aum Shinrikyo, British Israelism, Chabad, Jehovah's Witnesses, Moonies, Nation of Islam, Raëlism, Scientology.

ii) Carrier seems to be listing founders of religious movements. If that's his intention, then it's unclear why he includes Moroni on the list. Obviously, that's an allusion to Mormonism. However, the founder of Mormonism is Joseph Smith, or perhaps more accurately, Joseph Smith and Brigham Young were the cofounders of Mormonism. As for reputed miracles, it would be necessary to sift the documentary evidence. Keep in mind that Smith was a classic conman. His reputation precedes him. You'd must also consider whether his cronies had a financial stake in vouching for him.  

Maroni is reputedly the angel who appeared to Joseph Smith. But if, by Carrier's logic, that makes Moroni the founder of Mormonism, does that make the Angel of the Lord who appeared to Moses (Exod 3) the founder of Judaism? It's hard to see that Carrier is using a consistent principle when he includes Moroni on his list. Perhaps Carrier is simply confused. Maybe he meant to say Joseph Smith, but because he associates Moroni with Mormonism, he confounded Smith with Moroni. 

iii) If his intention is to list founders of religious movements, it's questionable to classify Moses as the founder of Judaism. Assuming Judaism has a founder, Abraham is as much a founder of Judaism as Moses. Perhaps we might classify Abraham and Moses as cofounders of Judaism. But Abraham didn't perform miracles. David is another central figure in Judaism, but David didn't perform miracles. It would really be more accurate to say Yahweh was the founder of Judaism. 

iv) There are no miracles attributed to Muhammed in the Koran. It's only in later Muslim tradition that Muhammad undergoes legendary embellishment as a miracle worker. 

v) "Superman" suggests an agent with innate superhuman abilities. By contrast, Moses is empowered to perform miracles. Moses is not a "Superman" in his own right. He's just an ordinary human being. 

vi) By contrast, Jesus does haven't innate superhuman abilities. That's because Jesus is God Incarnate. But that makes Jesus unique compared to the other founders on the list. So that example is disanalogous rather than analogous.

vii) Moreover, Jesus performed many public miracles. There were multiple witnesses. Furthermore, Jesus was a 1C figure, for which we have multiple 1C sources. Carrier needs to show comparable evidence in the case of Buddha and Lao Tzu. 

viii) It's true that miracles are attributed to Buddha. Buddha undergoes legendary embellishment. That's true in part because the sources for the historical Buddha are so far removed from his own time. They aren't reliably connected to the historical Buddha. As such, they can take on a life of their own.

In addition, Buddhism is mainly a religion of ideas rather than events, in contrast to the Judeo-Christian faith, which is primarily a religion of events rather than ideas. Buddhism was never essentially rooted in a historical figure. In principle, Buddhism could still exist even if Buddha never existed, for Buddhism is based on Buddha's "insight" regarding the problem of suffering. He's the founder of that religious movement because he's the first person to have that particular take on the problem of suffering (the Four Noble Truths, the Eightfold Path). But, in principle, anyone could independently hit upon that idea. By contrast, Christianity is subject to historical controls. 

ix) I don't rule out the possibility that some Buddhist or Taoist adepts might exhibit paranormal phenomena. The occult is a potential source of paranormal phenomena. That wouldn't disprove Christianity, for Christian makes allowance for supernatural agents other than God, including evil spirits.
