Cain's race is completely extinct (thankfully, they were literal giants who were as intelligent as they were wicked, and were they still around, they'd likely have put the jews to shame in their tyranny), your thinking of Canaanites I believe. Allegedly 50% of the jew's DNA is Canaanite, meaning they may have more in common with Israel's enemies than with the actual Israelites.
