I am suggesting that Eve in the Bible is not the mother of all the people alive on earth today. I can understand your conclusion from looking at that passage but that must not be what that passage means. Eve had two sons, Cain and Abel. We are told that Cain killed Abel and that Cain would be: "cursed and banished". "
Cain said to the LORD, “My punishment is greater than I can bear. Behold, this day You have driven me from the face of the earth, and from Your face I will be hidden; I will be a fugitive and a wanderer on the earth, and
whoever finds me will kill me.” (Genesis 4:13) What is this: "whoever finds me will kill me". Clearly there are people living outside of Eden (Adamah). This is what history tells us and this is what Science tells us. There were people living in Nineveh 9,000 years ago. We do not see Eve in the Garden of Eden until 6,000 years ago.
Göbekli Tepe Turkey is believed to be 10,000 years old. Yet Eve is in Eden 6,000 years ago. If we go back 40,000 years we find sewing needles and fish hooks made out of bone, along with fishing nets. These sort of artifacts go back long before Adam and Eve in the Garden of Eden. Chedder man goes back 10,000 years and from the DNA found in his tooth they found a living relatives of his working at the university in the nearby city. Again 4,000 years before Adam and Eve.
"THE WORLD’S OLDEST SEWING NEEDLE has been discovered in Siberia’s Denisova Cave, and it doesn’t look like it was made by
Homo sapiens. According to
the Siberian Times, the little needle was likely created by an extinct species of human known as the Denisovans.
The needle is made of an unidentified bird bone, measuring just under three inches long, and is thought to date back some 50,000 years. It even has an eye carved in the top through which to string thread. As the article points out, it’s probably still usable today."
