If you believe your soul is has always existed then it was not created by God, so do you believe the soul has always existed? The belief that the soul is immortal does not mean the soul has always existed, it just means once created it will never die, and I've never seen any biblical proof to the contrary (stating that each human soul has always existed), please point that out to me if I'm wrong, or consider that you're mixing new age heresy with Christianity.
