You don’t understand scripture as it relates to the creation of man. Why was there a tree of Life? Why would Jesus say is it not written in your law, I have said ye are gods, John 10:34 KJ, and David said, ye are gods, but will die like men, and fall like one of the princes, Psalms 82:7 KJV? Why would the fall of man be compared to one of the princes? And who are the princes? The princes are the fallen angels.
Please take a moment and digest the scriptures.
Man was created by God and was not suppose to die because man was created to live forever - and the Tree of Life would have made that possible. The Bible already tells you that if Adam had eaten from the Tree of Life he would have lived forever. So using reasoning, the question should be why did God put man out of the garden, and block the way of the Tree of Life? Based on Genesis 3:24 KJV, It’s obvious that God was stopping man from living forever.
But because of Adam’s sin, it’s obvious man was prevented from living forever - could not be made spiritual through eating of the Tree of Life - but would die like men, that is, due to sin, man had to be LEFT in “fleshly” bodies that could die. But if the sin had not happened, man’s fleshly body would have changed to spiritual bodies that could not die - become gods, children of God through the Tree of Life.
