The Earth isn't flat or a sphere because it doesnt exist. Mind Blown? It's because we are likely living in a computer simulation that is run by aliens.
That is an interesting argument. Personally, I doubt it, because the amount of processing it would take to emulate every single atom and the billions of pieces within it, to such perfection that
we never notice any deviation, is inconceivable to me.
We have a deviation, it's called "notbatman", so the simulation is obviously not totally perfect.
I bet the aliens are also enjoying Crysis @ 4k on their obnoxiously advanced hardware

were in a simulation we wouldn't be able to feel ''deviations'' anyways, in fact we wouldn't be able to ever know we are in a simulation unless we were programmed that way.
