It couldbe turtles all the way down. I’ve seen enough cosmologies that there are some that take a stance like that.
The simulation idea doesn’t work for me because a simulation needs to have an original that it is similar-to and simulating. The whole argument for that rests on a computer running simulations to determine the probability that reality is a simulation lol. Why did it say the probability is high? Because it is a machine and it always has a bias towards recognizig iteself lol. And then there’s the less rigorous argument that we might be in a simulation because we can create realistic simulations like video games. But we have realistic video games because we’ve specifically tailored them to create things that match what we see in the (you guessed it!) The Real world lol.
But, who knows about creation? It was a religious theme in the West from the Judaeo-Christian tradition, and it was picked up by atheistic technophiles as part of their religion of technology where the computer itself becomes God lol.
I’ve seen enough inherent intelligence in matter itself, I don’t even know if creation in a good term… It can very well be self-assembled.
But it is definitely not a factory or machine — that is a perverse view that projects our flawed cultural and industrial constructs onto the natural world. It is far more coherent and self-sustaining than anything humans have made to this date.
