Genesis 5:1-32

This is the written account of Adam's line.  

When God created man, he made him in the likeness of God.  He created them male and female and blessed them.  And when they were created, he called them "man".  

When Adam had lived 130 years, he had a son in his own likeness, in his own image; and he named him Seth.  After Seth was born, Adam lived 800 years and had other sons and daughters.  Altogether, Adam lived 930 years, and then he died.  When Seth had lived 105 years, he became the father of Enosh.  And after he became the father of Enosh, Seth lived 807 years and had other sons and daughters.  Altogether, Seth lived 912 years, and then he died.  When Enosh had lived 90 years, he became the father of Kenan.  And after he became the father of Kenan, Enosh lived 815 years and had other sons and daughters.  Altogether, Enosh lived 905 years, and then he died.  When Kenan had lived 70 years, he became the father of Mahalalel.  And after he became the father of Mahalalel, Kenan lived 840 years and had other sons and daughters.  Altogether, Kenan lived 910 years, and then he died.  When Mahalalel had lived 65 years, he became the father of Jared.  And after he became the father of Jared, Mahalalel lived 830 years and had other sons and daughters.  Altogether, Mahalalel lived 895 years, and then he died.  When Jared had lived 162 years, he became the father of Enoch.  And after he became the father of Enoch, Jared lived 800 years and had other sons and daughters.  Altogether, Jared lived 962 years, and then he died.  When Enoch had lived 65 years, he became the father of Methuselah.  And after he became the father of Methuselah, Enoch walked with God 300 years and had other sons and daughters.  

Altogether, Enoch lived 365 years.  Enoch walked with God; then he was no more, because God took him away.  

When Methuselah had lived 187 years, he became the father of Lamech.  And after he became the father of Lamech, Methuselah lived 782 years and had other sons and daughters.  Altogether, Methuselah lived 969 years, and then he died.  

When Lamech had lived 182 years, he had a son.  He named him Noah and said, "He will comfort us in the labor and painful toil of our hands caused by the ground the Lord has cursed."  

After Noah was born, Lamech lived 595 years and had other sons and daughters.  All together, Lamech lived 777 years, and then he died.  After Noah was 500 years old, he became the father of Shem, Ham and Japheth.

Again it is written that God made mankind.  As much as genealogies tend to be long and boring, the futility of the list seems to take away from the truth that people are special.  There is a reason God made people.  The genealogy also shows that God was not handing out empty threats when he said death would come from disobedience.  Person after person in the list were born, lived, married, and then they died.  There is apparently nothing in the long lives of these ancient men which applies to the purpose of the Bible.  It doesn't mean that their lives had no meaning.  It just means their lives did not have bearing on the coming of man's reconciliation with God, other than that they lived, had children, and died.  

Enoch and Noah are a different matter.  As far as Enoch goes, he apparently lived closer to God in some way than any one else.  It is not written that he did not sin, or that he was not normal. He took a wife and they bore children.  And then, . . . he didn't die.  Noah is extra special, as he does play a part in the coming reconciliation of man.

On another note, Adam was 130 years old when Seth was born, and so Adam was 235 when Enosh was born, and so Adam was 325 when Kenan was born, and so Adam was 395 when Mahalalel was born, and so Adam was 460 when Jared was born, and so Adam was 622 when Enoch was born, and so Adam was 687 when Methuselah was born, and so Adam was 874 when Lamech was born.

Adam lived another 56 years after the birth of Lamech.  Adam died 57 years before Enoch walked with God.  Adam died 126 years before Noah was born.  So, Adam was known firsthand to Seth, Enosh, Kenan, Mahalalel, Jared, Enoch, Methuselah, and Lamech, but Adam was not known firsthand to either Noah or his sons.  So, no one who lived past the flood had a relationship with the First Man.
