It’s been one of the most common Bible questions I’ve been asked over five decades of apologetics ministry—and people still want to know!

I recently filmed a video for our YouTube channel titled “Ever Wondered Where Cain Got His Wife? Watch This!” Within just a few days, that video had over 100,000 views. With everything going on in our world today, and all the big questions that need answering, why are people still wondering where Cain got his wife?

Because where Cain got his wife matters for the truth of Genesis. The Bible teaches that God created Adam and Eve and that every person is descended from them.

But who did their children, namely Cain, marry? If Christians can’t answer that question (and sadly, many cannot), it calls into question the truth of Genesis, implying that God’s Word can’t really be trusted. And if the history can’t be trusted, why should we trust what the Bible teaches about salvation?
