Even if humans manage to kill off most life on Earth it will continue to exist, propagate, and become more complex. Again we’re talking about billions of years. There have been huge shifts in climate and mass extinctions many times before and yet here we are.

True, it would be difficult to completely turn Earth into a lifeless rock, but I think humans are up to the task.

Eh I doubt it. Every single nuke ever built combined still doesn't come close to the power of the Chicxulub asteroid (the one that killed the dinosaurs) and even that impact didn't come close to eliminating all life on Earth. Unless someone accidentally compresses a mountain into an artifical black hole or something there probably is no way to wipe out all life on Earth.

Mars was once habitable but lost it's magnetic field, wiping it's atmosphere. Venus was once habitable but taken over by a runaway greenhouse effect.

I'm not saying they ever had life or that we're going to suffer the same fate, but it's definitely possible to wipe a planet clean.
