Only IF our birth is our creation. If we are indeed created before the creation of the physical universe which we probably all saw and were moved to sing HIS praises, Job 38:7, then we may have sinned before the foundation of the world and then sown, ie, born, into this world as sinners, Mtt 13:36-39, as sinful people of the kingdom and sinful people of the evil one.We are not born evil.
But I agree - NO ONE WAS CREATED A SINNER but only accrues sinfulness to himself by his free will choice to sin.
