Exactly my thought! Mass is a different state of energy, energy congealed or whatever form they call it. Einstein said this: “Energy cannot be created nor destroyed”...Of so, then that means it ALWAYS existed. And we know mass comes from energy. If that is the case, then there is no such thing as death. How can there be? If you take infinity into the equation, eventually that energy will form into you again. The monkeys banging on a typewriter will eventually write Shakespeare.
Maybe God is energy. But what kind of energy would He be? We may never get the answer to that. After that business with the Tower of Babel, it could be that all He wants us to know is that He exists and He is only one.
