Are there any stories where superman loses to a non mutant human?

The only story referenced in the evidence is the 1986 miniseries The Dark Knight Returns. In this narrative, Batman returns to fight crime and ultimately confronts Superman, who has become an instrument of the government. The summary does not state that Superman is defeated or that the battle ends in his loss. Without additional information or explicit mention of a defeat, the evidence does not support the claim that Superman loses to a non‑mutant human. Further sources would be required to confirm such an outcome.
