There are no humans or other species to kill off on life-barren rocks.
Has it been confirmed that no other species exist in the entire universe? FYI, everything that is sent to the space and vice versa passes through a process of disinfection to reduce the chances of infecting alien ecosystems with Earth bacteria which may be invasive. There are areas (with potential life) on Mars that are still intact by human machinery due to this exact fear. Space isn’t exactly life-barren, there’s bacterial organisms and maybe flora at the very least.
Okay, that’s fair. But in general, there are lots of areas in space that have a near-zero chance of containing life. We could easily enough verify that, say, an Earth-like planet lacked life as part of a probe and terriform process.
