Physics side of this theory?

Hello! I posed the scenario below in Religion/spirituality already, but I would like to see how people from Physics responds to this. I am a Professor of Religious Studies doing research in the feasibility of the self-creation of a god, which would involve Quantum Mechanics, Time, and all that, so I figure that I get some outside thoughts (For reference sake: Damn it Jim, I'm a philosopher, not a Physicist). I already have certain colleagues working on this, but I would like input from many areas, from academia and elsewhere.

Scenario:

~~~~~I will be using the term God in this example. I am not saying that there is actually a God or not, or which one. The only assumption is that the God in the example is able to create, destroy, and travel through time. Although a Spatial Mode can be applied, I will not do so in this example.

1. Let us assume that there is a single length of time labeled 'B'.

2. God begins to exist seemingly ex nihilo.

3. God's first action is to create a length of time after B, this one being labeled 'C', that's duration is irrelevant in this example.

4. God then creates a length of time prior to B, this one being labeled 'A'. He travels through time so that he is present in A.

5. While in A, since it is before both B and C, theoretically only A exists during that period of time.

6. God creates B, and then he creates himself within B.

7. The God of step 6 then travels in time to C, where he remains then on.

What are your opinions of this example of an Ipsum Creatio causal loop? Also, let us assume that it is not a God that did this, but rather a human time traveler, in such a way that it appears as the following:

1. The Universe exists as we know it.

2. A time traveler named Stewie is born at some point of time in this Universe.

3. Stewie uses his time machine to travel before the creation of spacetime.

4. Because of the time machine, there is a small "speck" of spacetime that manifests in a void that is without space and without time. This small "speck" shall be known as the Singularity.

5. Stewie overloads the time machine, spawning the Universe as we know it from that Singularity.

6. Stewie then re-manifested at a point in this Universe slightly after the events of Step 3.

7. The Universe from step 5 exists as Step 1 and eventually leads to Stewie's birth in Step 2.

This example can be called the Stewie Griffin Principal.~~~~~
