Computer simulations of real-world theoretical phenomena are propositions of potential outcomes that need to be verified through real-world testing to determine whether our modelling correlates with, or is skewing away from, reality.
No, it's pre-dictions. That's what the rest of your post says. Yes, simulations are one way of finding out what your theoretical model predicts. But evidence is the information from the real world that you compare the predictions with. There is no such thing as "pre-evidence".
