There are some very old questions in the origin of man. Most Christians answer it simply with the Bible, by discussing Adam, who is the first person mentioned in the Bible.
The Genographic Project, which was launched by Spencer Wells and National Geographic in 2005, is composed of a study of multiple blood samples collected by Wells. He looks at the samples as a piece of history, using each to determine an origin for humanity.
The studies link most of humanity to a single African descendant some 60,000 years ago.
On the surface, this could be Adam. But, studies have linked Adam and Eve to the beaches of Oman some 7,000 years ago, locating the Garden of Eden in the Persian Gulf–which probably flooded during Noah’s Flood.
Of course, there are other theories about these locations, but the time scale of Adam tends to vary from when the origin of man began.
Does this change everything about the Bible? Does the Bible actually say Adam and Eve came first? Not really. They are just the first people in God’s story.
But the Bible also talks about God breathing the “breath of life” into Adam. Maybe this is an initial creation, but it could also be a new program of humans. This could be similar to a computer that has all the parts, but has not yet been programmed.
It says that God formed humans from the dust of the earth. That was the physical part, but is that what’s important? Were there humans before Adam and Eve, but they were programmed different? What does it mean to have “the breath of life”?
