The 2nd Adam reported in the second chapter of Genesis is metaphysical, we will never know when he existed, but the truth is that there is a first man, ancestor of all men who believe in God.
The second Adam? Which translation are you using?
Genesis 2:7-8, "Then the Lord God formed a man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being. Now the Lord God had planted a garden in the east, in Eden; and there he put the man he had formed."
Genesis 2:15-24, "The Lord God took the man and put him in the Garden of Eden to work it and take care of it. And the Lord God commanded the man, “You are free to eat from any tree in the garden; 17 you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.”
The Lord God said, “It is not good for the man to be alone. I will make a helper suitable for him.”
Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. So the man gave names to all the livestock, the birds in the sky and all the wild animals.
But for Adam no suitable helper was found. So the Lord God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs and then closed up the place with flesh. Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man.
The man said,
“This is now bone of my bones
and flesh of my flesh;
she shall be called ‘woman,’
for she was taken out of man.”
That is why a man leaves his father and mother and is united to his wife, and they become one flesh.
There is only one man mentioned here: Adam. Where do you find a second Adam?
