"and we all agree the jewish christian god is a man made mythology, right? " yes i agree and not is it just the jewish religion of god, its every religion on this planet i dont believe, NONE of them. but i am also agnostic and believe there is a creator, and only because of evidence.
but if this was indeed a simulation, the evidence is just part of the simulation lol. how can you or me prove that this existence was not created upon my birth, and everything in it is just simulated? we cant prove god does or doesnt exist. i do not think that should be the question at all actually. i think we just need to keep discovering things and eventually our knowledge or physical bodies will evolve enough to let the question answer itself.
