That you have a soul worth is now being validated scientifically.  Medical science has recently confirmed you have a consciousness separate from your body in that:

      No stimulus to the brain can make you believe or decide anything.

      Stimuli to the brain can cause memories to play back or muscles to contract; however, these are perceived by the patients as external to their conscious “self”.

      Evidence from near death experiences denote conscious activity even during period of no brain activity; however, the amount of data is limited.

      Certain experiments have shown that consciousness of a specific event is delayed from the signals being registered in the brain.

Also, argument for the existence of your soul can be made from two compelling lines of reasoning:

      You have free will.  Your brain consists of nothing but matter, and for a given system of matter and conditions, has no options or free will; therefore, something separate from your physical brain must “cause” your free will: your soul.

      Most of the molecules in your change out every couple of weeks.  You would cease to be you, (you would be someone different), if there was no soul that provides continuity and remains “you” while your brain is constantly changing.
