Of course, but our sun going red giant is billions of years away, and will happen regardless of whether we're still here, taking good care of the planet, or not

Of course, but our sun going red giant is billions of years away, and will happen regardless of whether we're still here, taking good care of the planet, or not. I'm talking about what happens while earth is still in a livable state, even if maybe not for us. In the space of billions of years there could be many dozens of highly successful new eras of life each lasting hundreds of millions of years. From an evolutionary perspective humans are not the big deal that we think we are - we've only been around for a few millions of years (homo sapiens only for a few hundred thousand years) vs phases of life such as Triassic, Jurassic, etc that lasted for hundreds of millions of years. We may well wipe ourselves out via nuclear war, global warming, etc in the blink of an evolutionary eye, say in next million years - a failed experiment in intelligence that proves to not be sustainable, to be replaced by successive waves of new life exploring different directions.
