How do they know exactly how far away the sun is for example - it’s a theory. Just because NASA says it’s 93m miles away there is no way of proving it.

Einstein had plenty of theories. Science theories are actually neither proven or disproven.
Using calculations gleaned from parallax observations Cassini had a fairly decent stab at the distance involved - and that was in the 17th century. As we have far more technology at our disposal nowadays (including knowing how fast photons travel), we can now anticipate the movement of the planets around the sun (anannual event for us on Earth) in our solar system to such a degree that we can get space craft to return to our spinning and moving planet after weeks, months or years, wherever it is in relation to the sun. To imagine that the distance from the sun is only a theory is rather ridiculous. I think it's more of a case of not understanding how such distances are determined.
I don't like silly analogies but, with my cartographer's hat on, it's like saying that triangulation calculations aren't proven.
It's easier to dismiss science when you don't understand it.
