Take a look-see:

Forget about all the other intelligent life within this vast and
deeply complex universe that's supposedly going away from us faster
than we can possibly keep up with, much less overtake.  Even within
our vast Milky Way galaxy is simply of what's for the most part too
far away and moving further away at too fast of velocity as to bother
with, as that is how it works if you don't happen to believe in the
truth of stellar proper motions as having that pesky 225 million year
cycle that keeps bringing all sorts of stuff together.

Just one of many complex though otherwise good efforts for sharing the
most accurate of 2D animations on behalf of depicting our local
stellar proper motions, that's entirely relative as to our Sol that
not worth 0.0000001% (a billionth) of what otherwise every bit as good
or better for having hosted their own locally evolved intelligent
life, especially if such human intelligence only takes at most a few
million years under the right conditions.

This computer animated 225 million year galactic rotation or galactic
life cycle offers absolute loads of somewhat less massive stellar
cycles that are clearly of what's ongoing as much closer to our Sol,
that's specifically associated by way of that graphic blue dot
representation of our insignificant little solar system.

Though intentionally exaggerated, notice how extensive their expansion
and contraction cycle is, as for that graphic animation having
indicated as to how such stellar motions are far more interactive and
thereby entirely capable of influencing our environment, whereas so
much of that stellar activity becomes near our somewhat insignificant
solar system, so much so in that it seems somewhat impossible for the
likes of Sirius not to have become closely interrelated with us.

Perhaps there's a little less doubt we're unavoidably orbiting Sirius
(at least getting as close as 0.086 ly), and at such mutual encounters
whereas each of us becomes capable of exchanging a few icy and perhaps
even a touch worth of salty items, and/or exchanging a few physical
blows from within our respective Oort clouds of somewhat substantial
debris (especially from the robust Sirius side of this highly
illuminating and interactive Oort zone gauntlet).
