ELI5: Why do we care so much about habitable planets that are several lightyears away when there is no feasible way to get there?

always struggled to grasp this concept when it seems hopeless to get any outcomes or information. is the hope that we (or rovers) may travel at light speed at some point?

We're studying the universe around us, as we have done for practically all of human existence. We're so excited and focused on habitable planets because they're the most likely candidates to find signs of extraterrestrial life (as we know it). Just because you can't get to where you're studying doesn't mean you can't learn anything from it.
