All of the peoples in the Bible are still here, just under different names. A few examples are how “Mizraim” is translated “Egypt”, “Javan” is translated “Greece”, and “Cush” is translated “Ethiopia”.
BTW, all the peoples of the Bible? What are the Amekelites called these days?
How about the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites?
