I'm sorry to disappoint you but that is not a scientific approach. That an omnipotent being (should it exist) could have created everything we see and that even five minutes ago, is trivially true and therefore useless from a scientific point of view. There is no empirical way to either demonstrate the truth of that claim nor to refute it since every observation is compatible with Goddidit.
There is no mention of God, because the TOE assumes His non-existance.
And there is no mention of God or any other deity in other scientific theories either but somehow I never see creationists/IDers complain about that. So the Theory of Evolution no more assumes the nonexistence of your god than any other theory.
Also, not assuming the existence of a god is not the same as assuming his nonexistence. So science in general doesn't say that God could not have done this or that. At most one can say that science only claims that he need not have done it.
You have been keeping up with some of the attitudes from some scientists in astrophysics and quantum mecahnics, etc.? I seem to recall many quotes about God from some pretty prominent scientists. Oh yeah, a lot of folks here will explain their own "interpretation" of what that scientist "really" meant. But that's not much different from the M.O. of a fire and brimstone bible literalist preacher.
