We have a very intuitive sense of asking "what's happening right there at this time". It's a super simple question and it's how we want to understand black holes. Like, after it collapses, what happens to the stuff inside? What if there was a planet? Etc. The question necessarily treats space and time as two seprate entities, which generally works fine. Relativity starts to break that question. Different inertial/non-inertial observers will get different answers. Not a huge problem for physics, because we can easily figure out the answer for each observer. But if it was super important to you what event happened first, you won't get a satisfying answer, unless the two events occur inside each other's light cones. Then there's no ambiguity. So we get to black holes, they seriously break this question, the light cones are completely messed up.
