But do you know what's killed even more species than humans have?

A supervolcano.

And what killed even more species than that?

An asteroid.

And honestly, the world has very little to show for it.

Mass extensions happen, they've happened many times and they will continue to happen for as long as there's still life in this planet. So sure, humans are causing a mass extinction right now, but (A) that's not unique or unusual for the planet, and (B) we're aware of it, and we're trying to change (even if we're mostly failing). The asteroid never even tried to turn around, so in that sense we're already proving friendlier than nature.

And on the topic of asteroids, here's another thought... NASA's DART mission has made meaningful progress in our efforts to prevent the next mass extinction by redirecting an asteroid. What that proves is that we are capable of doing positive things for the planet. Our self awareness gives us incentive to protect the planet and ourselves. I would think that the combination of our incentive and proven ability likely means that the planet is better off with us than without us, but in the end we'll just have to wait and see.
