"Ben" being the alias isn't any more-or-less an elaborate solution than "Obi-Wan" being the alias.

Except that "Ben" is a name, while "Obi-Wan" is some strange mystical title.

But you know what? You guys are right. We need to get to the bottom of this deep perplexing enigma.

And while we're at it, we need to figure out why they kept calling Mark Hamill's character "Luke Skywalker," since it's my subjective opinion that his name is actually Schnarzle Shnuzzle. It just doesn't make sense!

Damn you George Lucas for never explaining why they all keep calling Schnarzle "Luke"!

Damn You!!!!!
