ps There was also a Krypton story that space exploration experiments had been banned, after Jax-Ur blew up Krypton's moon, Wegthor. For that crime he was exiled to The Phantom Zone.

Elliot S. Maggin had this to say on the topic years ago:

"The idea was that the baby needed to be cast across the sea of space and arrive alone, unknown and innocent in a foreign place. That's the outcome that creates the legend. Given that, the most effective explanation is the simplest one:

Jor-El had built a small prototype craft and was working on the family-sized model, but the end came sooner than he could have hoped. There was only room for one and he begged his wife to leave, but she insisted her place was with him. They all faced certain death, so they took the only member of the family who couldn't object and sent him to be found abandoned by the side of a road.

I actually know a little girl who was found in a basket by the side of a road in a country dismembered by poverty and war. Someone picked her up, dusted her off and saw to it that she was adopted by a nice couple in a very foreign place. She's twelve now, brilliant, prepossessing and quite beautiful. She's gradually developing super-powers of her own. The world would have been much poorer without her.

See? Metaphors are real."

And Beppo?

 
I have no idea who that is.

Well, I do now as I’ve visited Wikipedia. 

Beppo is awesome.

It’s not his fault that comic books are stupid.

Hey, we at the Sam Simeon/Angel & the Ape appreciation society have something to say about that!
