I believe that wholeheartedly.
I believe it because Genesis 1 and 2 describe that clearly.
But I also recently was thinking through Acts 17:26
“And he made from one man every nation of mankind to live on all the face of the earth, having determined allotted periods and the boundaries of their dwelling place”
God made every nation of mankind from one man, Adam. Adam was the first human. Eve was the first woman. And from those two, God populated the entire earth.
I believe it.
