[Quranic Reflection]: God is the light of the universe.

[Deesse23]

That's why we can't see him. .... he is the light itself:.....The light of the universe.

We have can detect (all across the universe)
Radio
Microwave
Infrared
Optical
Ultraviolet
x-Ray
Gamma-ray
Cosmic -ray

I have not read yet about a paper that claims to have detected him. He seems to be undetectable, and thus indistinguishable from a nonexisting god. After all, universe creating pixies also could be "the light of the universe" and its been those Pixies that are hitting our detectors all the time.
I prefer to believe in Pixies, at least they are far less violent than your tribal warlord god.
