That is an interesting perspective, and I personally believe that the concept of God is something each one of us must harvest inside ourselves, on our own, and in our own ways. However, your proof is simply not definitive. It does not prove that God, as the popular concept, exists, not even close.
You make the following assumption which you (and anyone else, for that matter) are unable to prove: that you are indeed omniscient and omnipotent. You say it, but unless you can back it up with definitive proof, the rest of that does not contribute anything to strengthening your argument.
Humans' perspective is extremely limited, and they can be easily deceived by things like brain chemistry, mental capacity, and other factors, that is why it is impossible for ANYONE to prove or disprove the existance of God.
Nice try though!
