> Now, regarding physical models, you are assuming there is a universal truth or reality that is the same for everyone. And that is just a belief.

Can we prove that the laws of physics are the same for everyone? No. That's an assumption. It seems to be a reasonable one, but it's an assumption.

But we got to our current understanding of physical models from other ideas. [Edit: That is, other ideas of what the models should be.] How did we get here? By people believing other things, and them finding out experimentally that things didn't work that way, even for the people who believed that they did.
