Hypothetically speaking, if Adam and Eve were real, how did they populate the earth? (Description)
(I'm Christian but don't fully believe in Adam and Eve) so lets say we have Adam and Eve, they have 2 children, a boy and a girl. then what? how did that populate the earth? wouldn't it just stop there? wouldn't the offspring of siblings be disabled in a way? I don't understand how the story of Adam and Eve makes sense.
