I don’t think Adam is Jesus
I do know that sometimes in The Bible when it refers to something it’s referring to 2 things and not just one thing
This is very common in prophecy
It’s referring to Adam but ultimately as referring to Jesus Christ
It’s referring to more than one person
Romans 5:14 - Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come.
Though the bible does say that Adam was a type of Christ (In that he was created in the image of God, and Jesus is God) it is not referring to more than one person. Adam is clearly one person as was Jesus. I recognize that there is certainly room for alternate interpretations…I read Genesis 2 as a distinctly different human creation than the creation of the “animal” human. I think the distinction is that Adam was given God’s spirit by God breathing life into him. Also, that Adam was the first of “God’s chosen people” and it was necessary to make him different from other humans. But, that’s just my take on it…
