That’s a gross misrepresentation of anything that’s been said that goes counter to your own position. There is no disagreement that Adams fall impacts all mankind, the disagreement is HOW. The most I gather from your (and others) position is that Adam passed down some sort of “sin gene” and thus death to mankind. This mythical change in Adams dna that we all carry is the reason we die, babies die, everyone dies. That idea is an invention you base on scripture you misinterpret.What I find intriguing is that the entire creation has come under a curse as per Romans 8 &c, and people accept this truth, but then say man get's to choose to obey God just like Adam, and if not then they become sinners like him. It is as if the universal consequences of the fall do not apply to them until they exercise almighty free will. Man-centered nonsense right there.
The Bible says that when God banished Adam from the garden, He directly attributed Adams eternal life, and thus impending death, on his eating from the tree of life. Genesis 3:22 makes known that it was eating from the tree of life that Adam could live forever. There was no magical change to his body inherently that caused death. Death came to all men by Adam because by him, man lost access to the tree of life. By Jesus, man regains that access (rev 22:14). Romans 5:19, through Adam MANY were made sinners. This born/conceived sinner nonsense is unscriptural.
