The does not mean he would be the most recent common ancestor of everyone, or even of every Jewish person.
Actually according to the Bible there will only be 144,000 pure descendants during the tribulation period. 12,000 from each of the 12 tribes. Rev7:4 "Then I heard the number of those who were sealed: 144,000 from all the tribes of Israel". The people that do not go in the rapture will still be on earth to see this. The Church will be gone and Israel will give a witness and a testimony for God.
AAron was the tribe of Levi so we already have the genetic marker for that tribe. (Cohen Modal Haplotype (CMH)
5 From the tribe of Judah 12,000 were sealed,
from the tribe of Reuben 12,000,
from the tribe of Gad 12,000,
6 from the tribe of Asher 12,000,
from the tribe of Naphtali 12,000,
from the tribe of Manasseh 12,000,
7 from the tribe of Simeon 12,000,
from the tribe of Levi 12,000,
from the tribe of Issachar 12,000,
8 from the tribe of Zebulun 12,000,
from the tribe of Joseph 12,000,
from the tribe of Benjamin 12,000.
What we are showing is that the genealogies in the Bible are accurate and true.
Adam, Noah, Abraham, Moses, David & Jesus were all real people and they were all related to each other. We have genetic evidence for is AAron brother of Moses. This is called the
Cohen Gene. We also have evidence for Abraham. Once we see we have evidence for
Aaron and
Abraham then it does not take a lot of faith to see that
Adam and
Noah were real people also.
As a Christian it is important to understand the dispensations and the
covenant God has with mankind. God established a
Covenant with
Adam, God established a
Covenant with
Noah and mankind after the flood.
Genesis 9:12 "God said, This [is] the token of the
covenant which I make between me and you and every living creature that [is] with you, for perpetual generations:"
God established a
Covenant with
Abraham and his
descendants. Even those who are adopted into the family of God. Abraham was told that he would be the father of many nations and that is exactly what happened and the DNA evidence shows that is true. The evidence that has only been available to us for a few years. Yet that DNA evidence shows us that what God told
Abraham in the Bible is accurate and true.
Genesis 17:4 "As for me, behold, my
covenant [is] with thee, and thou shalt be a father of many nations".

Matt 1:17 "Thus there were fourteen generations in all from
Abraham to
David, fourteen from David to the exile to Babylon, and fourteen from the exile to the Messiah".
We have all the DNA evidence we need to know that Abraham was a real person. Because that evidence shows us that the generations or the genealogies in the Bible are accurate and true. It is what it is, to argue about it is pointless.
Titus 3:9
But avoid foolish controversies, genealogies, arguments, and quarrels about the Law, because these things are pointless and worthless.
