Those Pagan Kryptonians!

A rather surprising response from Weisinger, who generally portrayed Krypton as far more advanced than Earth. Of course, you can see the problem; if he responds that they had some different kind of religion (or no religion at all), he's implying that's superior. So he almost had to come up with the answer that he did.

It does raise an interesting point, though. Surely Clark was brought up in whatever religion the Kents practiced, most likely some form of Protestantism. And yet his creators and longtime editor and publisher were all Jewish (which is probably why, after the Golden Age, there were almost no stories that mentioned Christmas or any other religious holiday).
