"has existed long before humanity" isn't relevant for my argument.

"Will exist long after humanity" -> maybe, maybe not. If we're smart, capable and humble enough, we could, in principle, intentionally outlast them.

By "intentionally" I mean: we can design our future lightcone such that, by whichever measure you care to choose, there are still humans around. Yes, bacteria could be still around, but it won't be because they _chose_ to be around, it will be because it just so happened that the universe arranged itself in a way that they are still around.

By "in principle" I mean: if we spent enough resources, energy and smarts and built a civilization around this goal, we could plausibly (given the known laws of physics) do this. Whether we _will_ do it or destroy ourselves first any of the possible various means, is an open question.

Lineages of bacteria that exist today, here, will only keep existing in the _far_ future (billions of years from now, after the sun chars Earth and then spends its energy budget) if it just so happens that a panspermia event kicked some off our solar system and then they just so happen to find a suitable solar system to keep existing.

We can design our future, bacteria can't.
