A computer can only execute one instruction at a time. The only way reality could work is by trillion trillion individual independent agents each acting on it's own interacting with others. a single computer could never create all the actions the agents are taking at the same time. for example there are 8 billion humans on this tiny planet . Each is doing something different at this time . a single computer could not simulate each action which is a universe itself at the same time. The thought that i'm having at this micro-second is different from what you and 8 billion others are . a human can think at least 1500 words per minute. a computer could never run each humans actions and point of view at the same time. my finger is reaching for the keyboard as you are doing something else 1000's of miles away.
a single computer would have to be able to change every entity in the universe every electron every human at the same time and know all the changed information that happens at the same time for example what i'm thinking and you are thinking at the exact same moment , know all the information from all parts of the universe from septilions of changing agents at the same time : this is impossible.
each individual human is composed of 30 trilion human cells . every cell is huge factory a universe itself . the cell is copying DNA, creating many proteins , getting energy AtP hundres of processes at the same time each cell is doing , many process are going inside machines inside the cell at the same time. then the cell is composed of quadrillions of atoms with electrons . each electron is an entity , each moleccule an entity an agent . each molecule like a human is interacting with other entities / agents. the computer would have to similuate each electron and it's movement around the atom it's interaction with space other particles etc. at the same time simulate ( no create) and control each of septillion of electrons in a human or cell all at the same time then on the 8 billion humans .
I think it's a common falacy to think that a single god, single computer , single intelligent being has to run manage everything from the top down from a single point . that as i tried to show is impossible. simpler agents like molecules interact with others and form more complex interactions and structures from the ground up. this is how life started. it's a common antropocentric falacy to think that only the vaunted Human intelligence or human like intelligence could create , manage and run all reality. when it's impossible for a single intelligent entity to do anything other than work on one single thing at a time .
It's like one human trying to run all the tasks that every human is doing all 8 billion at the same time . a human couldn't ever it's impossible for a human to do even 2 tasks at the same time. same for a computer . the human intelligence is much weaker than people are taught to believe. the only way a human can get anything done is by working on one thing for at least a few hours straight every day a single task a single non trivial problem or goal
below is ahow a computer can simulate an image on a screen. it only requires a very small data a few numbers to do that. the human it simulates is 8 trillion cells each interacting , trillion trillion molecules , 39 trillion bacteria inside the human. . of course more numbers to create more resolution. but to a human they can say that is a woman or a picture of a woman. it's not . it's numbers in computer memory copied to the screen as pixels. you can see the image of a woman is represented / similuated with just numbers. this is explained in the link below. more pixels / squares and higher resolution so that it looks like photo but if you look closer it looks like this pixalated and you can see each quare is just a very weak low resultion of reality . it's an illusion not real reality.
Before we look deeply into how machines read images and use them in computer vision, it’s important to underst

I'm a computer programer . i know all the work that a computer has to do to update a single pixel on a screen. many asembly language instructions. It's very difficult to write code. there are a number of inherent bugs / errors in every 1000 lines of code in existence.
i'm just touching on this . this shows there is no god / programmer / computer that is managing controlling creating every interaction in the universe at the same time because that is impossible for a single entitity to do .
