I only brought up the that the First Law of Thermodynamics as a starting point for conversation. Sure Matter can be more than Stuff, but we had to start somewhere. So do you think that The Second Law of Thermodynamics, applies to the conversation?


And yes the the Big Bang Theory violates the first law of thermodynamics. But that still doesn't explain where the Matter of any kind comes from.
