Mine is not a variation on the assertion that God created the universe with an apparant history.
It is based on Physics and Scriptures. If you really want to know more you can find it at Freeper Views on Origins
Your assertion does not prove your assertion. It is perfectly possible to establish a coherent mathematical scheme in which we are on the inner surface of a sphere and the universe extends towards the center of the sphere. Such exercises can burn a bit of computer tim getting all the physical laws adjusted, but they contribute little to understanding.
Does your expansion model make any pridictions that would differ from the predictions of ordinary physics -- for example does it predict anything along the lines of cosmic background radiation or the polarization thereof, that cannot be accomodated by traditional theories. If so, are your predictions quantified and on the table for confirmation or disconfirmation?
