Exactly. The simulation theory proponents almost always seem to presume the existence of some sort of being that deliberately created the simulation. What if the simulation is a complete accident that has arisen from the complex interaction of brainless bacteria competing for scarce resources on the surface of a big rock? An accidental simulation emerging from randomly initialized 'cellular automata' on one rock in a host universe containing trillions of such rocks.
The usual presumption of the simulation being a deliberate construction of a conscious being makes the whole thing seem like nu-religion for people who reject supernatural things. With the presumption of a being deliberately creating the situation, you pull in these notions: We're special, we exist on purpose, we are probably being examined and judged. This reeks of religion.
Because even if our reality came from that rock bacteria, we're on the cusp of creating simulations within and statistically beings may still expect to be in a deliberate simulation, if we think we'd eventually simulate more beings than exist.
The rules of the presumed host universe are unknown, but which do you guess is more common in ours? trillions upon trillions of rocks, may of them probably covered in organic goo interacting with itself, or intellectually sophisticated computer scientists deliberately designing simulations? I think it's got to be the goo.
