Newtons laws actually do an amazingly good job of describing motion in the realms of physics we typically interact with. Newtons laws aren't wrong, for things like making an airplane fly and boats float, or things like throwing a ball/shooting an arrow/shooting a bullet, they're just incomplete when you look at the "extremes" like inner planetary orbits. The main reason Einstein is so revered is because he was able to develop a theory and equations that do accurately predict what had been observed.

Almost certainly Einsteins theory is similarly incomplete, we just have to find the extremes where its predictions don't agree with experiment and then understand what the experiment results actually mean and what could cause them.

One thing to always remember is that all these laws and theories and equations are just ways to model and predict the reality we experience. All models are wrong. Some models are useful.
