Adam & Eve and Cain & Abel and Mrs. Cain?

OK folks...now let's look at the facts:

"God fashions Adam from dust and places him in the Garden of Eden where he is to have dominion over the plants and animals.   God places a tree in the garden which he prohibits Adam from eating.   Eve is later created from one of Adam's ribs to be Adam's companion.   However, the serpent tricks Eve into eating from it.   God curses only the serpent and the ground.   He prophetically tells the woman and the man what will be the consequences of their sin of disobeying God.   Then he banishes the man (and presumably also the woman) from the Garden of Eden."   I know, I've written about this before and you can't believe everything you read in Wikipedia...but still!

BTW...

At the historic Scopes Trial in Tennessee in 1925, William Jennings Bryan, the prosecutor who stood for the Christian faith, failed to answer the question about Cain’s wife posed by the ACLU lawyer Clarence Darrow.

Consider the following excerpt from the trial record as Darrow interrogates Bryan:
Q - Did you ever discover where Cain got his wife?
A - No, sir; I leave the agnostics to hunt for her.
Q - You have never found out?
A - I have never tried to find.
Q - You have never tried to find?
A - No.
Q - The Bible says he got one doesn’t it? Were there other people on the earth at that time?
A - I cannot say.
Q - You cannot say. Did that ever enter your consideration?
A - Never bothered me.
Q - There were no others recorded, but Cain got a wife.
A - That is what the Bible says.
Q - Where she came from you do not know?

As you well know, Cain killed Abel!   So I thought it was just the three of them left...Adam, Eve & Cain.   No?

But then again...according to Genesis 5:4, there was also a son named Seth and Adam lived 800 years and had other sons and daughters!   This all depends on which version of the Bible you follow and are you going with the 800 years in Genesis 5:4 or the 930 years in Genesis 5:5?   Either way...somewhere in there, Cain must have married a sister and they had a kid named Enoch?   I'm puzzled...but that's nothing new!
