The laws of physics teach us that every action has a reaction. However, they never state that every action is a reaction. If we had the ability to trace every effect to it's cause would we stumble onto an origin cause?
Or is something just as strange going on, and everything has just always been. Ever flowing, and stretching to eternity in both directions of the time line. Is every action a reaction simply because there was never an origin action?
Yeah that's some pretty twisted logic, but these problems don't go away just because of your beliefs. Though they may make your acceptance of the answer easier. What created your god, and what spurred it into action, if we are living in a simulation why do our simulators not face the same conundrum?
Maybe reality is just a set of dominoes, infinitely toppling with no beginning or end. I don't know man, but whenever infinity comes up in science it sure does make my brain hurt.
