Good thought... Adam was designed to live forever. In a sense, he had the body that we will one day inherit once we cross over into eternity. He was genetically perfect and pure -- EVERYTHING that God intended to design into we humans, as was Eve. Just imagine what that means...
Ever met a true genius? How about someone with a true photographic memory. What of the man who can run sub 4-minute miles, or those who can run marathons in mere hours instead of days. Strength, intelligence, acuity, feelings, emotions, soul, etc., were all declared by God, "very good." We can piece together what that "very good" man looked like by taking all the best attributes of humanity and wrapping them up into one person. It is only the infiltration of the evolutionary worldview that causes us to think that we have evolved to a point of superiority to Adam (or even early humans) when in fact, we have "de-volved" by genetic impurity, etc. Of note, God did not declare children by brothers and sisters impure (incest) until well after Noah. It is only as the curse of the fall has de-volved our genetic structure that this requirement was even necessary.
