I guess the simulation theory is an atheist creationist'ish belief.
And it's hard to argue with that theory, since in a sim the bots world is updated at a certain framerate and it would never be able to move outside those confines. So if we're just an advanced evo sim, we would never be able to find out, and as mentioned the behavior of electrons still eludes us and it would be a more or less valid theory that things work this way because the physics in our world are just the sim settings but when you look at the smaller bits things behave very oddly.
And as crazy as the theory may be, wouldn't it be awesome if we where actualy just a simulation... making out own simulations. (Maybe we can get that ball rolling around DB 1000)
