Just think about it this way...
IF the Bible is correct, then;
We're descended from 2 people originally (Adam and Eve), plus they must
have in-bred their own children with Eve (they only had sons, right?)
Next, we're then descended from 12 people (Noah & wife, his 5 children
and their spouses)
So, we are already so in-bred that it just doesn't matter who you meet,
you're related to them <g>
