And yet we find respectedscientists some atheist making the same formulations as classical theism...
Still drivel. It's nothing like classical theism. Characters in science fiction that simulate universes (to some unspecified level of complexity and extent) are simply not anything like classical monotheism. Having one similar characteristic does not make two concepts the same.
The sun and my phone both produce light, so my phone is the sun, according to Vlad-logic.
Some try to blind us to this by ad hominem the personal creator they have generated by suggesting its Kevin the nerd.
As the created we have imho a better argument to say from thiis universe that it was closer to the metametaphysical God of philosophy rather than a Kevin which is almost obviously an argumentum ad ridiculum.
The point is that, because you've only tied down
one aspect of this pseudo-god, it literally could be
any being or beings at all that use technology to do simulation (it could be Kevin, it might be an evil mega-corporation or the criminal underworld). It's closer to a
reductio ad absurdum (which is a valid argument) than an attempt to ridicule. It emphasises the
basic logical mistake you've made in thinking that one characteristic in common can be used to make concepts equal. Specifically the your "argument" for "god" could lead to something very unlike any classical god of monotheism.
