They married the daughters of Adam and Eve. Duh.
So all three races,Caucasoid,Mongoloid and Negroid are descendants of Adam and Eve,right?
Right answer.
Every Christian apologist is tired of this question. People rarely ask it out of genuine interest or curiosity, rather they seem to think that it is a self-evident, self-refutation within the Bible, as if the Bible is just another mythological storybook.
Then when you say he married his sister, they persist saying, “That is incest!” That is another type of internal contradiction, that the Bible contradicts its own morality. so then you must discuss what incest actually is and why or Who makes it wrong and how. It isn’t incest, it is actually consanguineous marriage. In some states, you can still marry your first cousin even now.
Next they question that there could be any number of daughters of Adam and Eve not named in Genesis, to which I respond with,
“In the Bible women don’t count.”
“What?!”
“You know like in the feeding of the five thousand, it says 5000 men, and no count of how many women and children. Women and children don’t count.”
And then, “That is so sexist!!”
There it ends.
