Yup, I sure do and your semantic nit-picking does not change the fact that you cannot simulate reality, that computer models are abstractions designed to prove what the designer wishes.
Then there are hundreds of thousands engineers and scientists who model everything from chemical processes to hydrogen bombs, buildings to bearings, electronics to automobiles who don't exist in your mind...
Ever hear of ANSYS? SUPREM? Spice?
No? Didn't think so...
If you would take a second to read your own words for understanding, instead of for decibel level, you might fathom why this is such a silly statement.
...
What you mean to suggest, I expect, is that you cannot model reality with perfect fidelity and detail, which is, indeed true, however irrelevant.
