God is energy, light is the electromagnetic spectrum, energy = E=mc^2. What, don't believe in Relativity? God said "let there be light" and as close as you can get is .01 milliseconds from that creation in your explanation. When you get the rest of the way let me know and everyone will know how god did it.
All science will tell you is that they think it all started from a primordial singularity, yet all their vaulted knowledge and wisdom is layed low, because no matter how hard they try the math breaks down. No explanation for the beginning of it all, but they know for a fact it was not created. What, did I miss something??? Do you not require an unexplainable miracle to start it all???????
So unexplainable that all you can get with math is a beginning something, alone in a universe devoid of all matter. And then Wham (insert miracle here) the universe is born. But how did the primordial singularity exist in the first place, never mind you cant yet explain that singularity banging. So your theory follows the same path, god said let there be light and there was. Man says let there be light and there was.
