Simulation... I just don't buy it. İt's is too complicated, nonsensical and full of compromises for a such theoretically intelligent design with unlimited creative opportunities.

Atomic-molecular based structure would be stupidly expensive and demanding process to simulate. Smallest known single celled organism is made up of hundreds of thousands of atoms and they are everywhere in who knows what numbers. Average human is consisted of 6.5 octillion atoms. Then, those atoms have their own properties like variations, in hundreds and they also decay and form bonds and convert into others, release energy and etc. Random particles is all over the place, radiation and etc. Too much chaotic, totally unnecessary and expensive stuff. We humans are much simple part of it all. 99.9% all every goes to stuff. We're the OG creator(s) simulating the universe and we are side quest for them? All those, microscopic and sub atomic stuff around and beyond our observations, we do clearly see the logical sequences and trails of their effects, so they are not in purely "exist on demand" status. 60 iq Hunter-Gatherers used bow and arrows long before we knew about basics of ballistics, untill someone questioned nature behind it. Now we are that stage with more grandiose stuff, like quantum physics, consciousness and etc.

We can make slow-motion cameras that can take a million to 10 trillions of frames per second, where can see light travel through mediums and stuff. We can have our own supercomputers that simulate a simulation inside a simula-AGHH!!! At this point it's not even a simulation. I'd argue that perfect "simulation" and analogous existence is the very same thing.
