That point of view is inherently untrue. We have an extremely good understanding of how the universe works. The Standard Model has been worked on since the 40's and has been experimentally proven and refined ever since. There are things the SM doesn't account for yet, such as dark energy, dark matter, and gravity. That doesn't mean it's beyond human understanding, just that there's more to the universe we haven't discovered yet. In the worst case, those things will have interesting but not surprising answers. Slight modifications to the SM to account for some new particle types, etc. In the best case, they turn out to be something completely unexpected and the SM turns out to be the equivalent of Newtonian theory. Perfectly good and accurate theories about the nature of the universe that are just a subset of a wider physics model, like how Newtonian theory exists within the Standard Model.
