Remember: “All models are wrong. Some are useful.”
True direct proof only exists within the most raw philosophies like mathematics. All else is comprised of theories which we haven’t proved wrong yet or, in a few cases, the least-wrong of all our theories.
Quantum physics and relativity fall in that final category. They describe the universe well but not entirely and not together. We know they aren’t currently correct, but they are the best we have at the moment.
