Light powered lightbulb

Oh... this is not an easy explanation....

Let's say that anything and everything consists of light moving at light speed. The point at which it materializes is a point in which light energy converges from all directions at once. So If we were to be cut from the source of energy in our universe for a brief moment you would disappear and reappear without knowing the difference.
The universe not ourselves is the material origin of existence despite most assuming it is a concept that is very far from their own minds..
