Thanks
for the question. Your assumption is correct.
We are all related. As a matter of fact in the New Testament in Acts
17:26 Paul preaching to the people in Athens said, "And He has made from
one blood every nation of men to dwell on all the face of the earth, and has
determined their pre-appointed times and the boundaries of their
habitation."
When you go back in reading Genesis not only did all people come from
Adam and Eve but as the creation continued they came again from Noah and his
family when the world was destroy by the flood.
The different races and generations are to be traced from the sons of
Noah and from the separation which took place at the tower of Babel as
described in Genesis chapters 9- 11.
I
hope this is helpful to you and if you have further questions please feel free
to ask.
