Is there reason to believe that God created us as human souls and our transgression made us physical which is why we are to resist the temptations of the flesh, and why we are not " of this world"? Because being physical is of satan? Because if we were of Gods alone, we would not be born sinners.
We're not born sinners-God doesn’t create sinners or sinfulness to begin with. This world is a place of education and formation; we're here to learn how well we like
autonomy from God, in a world free effectively from His moral control, unsubjugated to Him. That’s what Adam opted for, becoming his own “god" in the process. Because man’s distance or separation from God is the essence of his spiritual death, a state sometimes referred to as “original sin”. We’re born without the “knowledge of God”, and Jesus came, when the time was ripe, to show us His true face so that we may know Him, and so come to believe in, place our hope in, and, most importantly, come to love Him, becoming willfully subjugated to Him in that process, reversing the orientation of Adam
away from God. We’re to find out what Adam missed (and presumably knows by now), to find out about our absolute need for God and the perfection of His wisdom for our lives-so we’ll increasingly heed Him, as Adam failed to do.
Everything God creates is good, including our bodies and natural appetites. The problem is that, if man isn’t spiritually and willfully subjugated and bound to God, a relationship that’s authentic and meaningful to the extent that we love Him, then we’re sort of wild, not necessarily obedient to His voice, free from the law He wrote on our hearts (even though it still exists inside), questioning the moral correctness of this act or that, uncertain about what we should or should not do morally speaking. Adam opened the door to moral relativity, and all sin that followed was then inevitable.
