On the two Adams and the Socinian/biblical unitarian paradigm

   1Corinthians ch.15:47NASB" The first man is from the earth, [s]earthy; the second man is from heaven."

Luke ch.3:38NASB"the son of Enosh, the son of Seth, the son of Adam, the son of God."

If we take the Socinian/biblical unitarian position it seems odd that either Adam should be spoken of as originating from heaven.

And if this originating from heaven is figurative language for the extraordinary origin of the second Adam. How can anyone argue that the origin of the first Adam was less distinctive? 

Unlike the second Son of (the)God the first was not also son of (the)Man.

JEHOVAH's Archangel breathe the first breath into the lungs of the first Adam see Genesis 2:7. What could be more distinctive than that?

From a Socinian perspective it seems that the first Adam is much more worthy of the titles

son of God and Lord from heaven in terms of his origin.

Romans ch.5:14NIV"Nevertheless, death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam, who is a pattern of the one to come."

The first Adam is the prototype . How can any man born of a fallen woman possibly have more of a claim to the title Son from heaven than him if the Socinian/biblical unitarian paradigm be true?
