Cain Was Afraid .. of Who?!?

Were other people created by God besides Adam and Eve?

I have been asked many questions of this basic theme over the years.  The answer is quite simple: the Bible doesn't say.  I think the phrase "I don't know" seems almost alien to many Christians who, in err, feel that if they can't answer every question, then somehow they fail God and His sovereignty somehow dissolves.  It's ok to say it ... the fact is that if a sovereign god exists and we, through mortal and finite understanding, can fully understand and explain him, her, or it, then the god we represent is no god at all.
