Its kind of funny to think there are more aliens out there that wonder if there are aliens out there than there are aliens out there that know there are aliens out there.

So what we are really seeing is their old photographs and some are actually gone now
If aliens have come, if they weren’t traveling at the speed of light or immortal, they would have to be a being that lives an insanely long time
Most likely they didn’t come in person because of the distance. Most likely they may be all gone by now. Most likely what they sent to reach the far parts of the universe to them is what we send to reach mars. An un-manned craft like Curiosity, still working to complete its programmed mission even after its designers are gone
That’s my guess
Time dialation is really cool. Zoom away from the solar system at near the speed of light eventually looping back. Wind up in the future and meet your decendents.
This is probably one way to survive the expansion of the sun or death of our biosphere. Enders game books has the last guy to win the war zip out on a four year journey and meet up with the next Supreme commander in 50 years or so. No reason this can't happen over two or three generations at 1g constant acceleration.
Driving as fast as we can straight towards the center of the galaxy has weird temporal effects 2 iirc. Like it may take a thousand years and yet millions or billions of years pass at the point of origin.
I'll posit this question to all you space nerds (and I'd really love a legitimate answer)
If the Earth is revolving around the Sun, and the Sun is flying through to galaxy, and all the other stars are doing likewise, and yada yada yada. WHY is it, that we have seen the exact same constellations in the night sky for thousands of years ? Shouldn't this shit be, oh I dunno, moving ?

Can’t tell if this is a serious question or a troll. But I’ve been dating a research professor of astrophysics who studies galaxy clusters and black holes for about 6 years now. So I’m basically an expert. And if you’re telling me all she’s been doing for this whole time is going to work and watching YouTube videos I’m gonna be pissed!
The short answer - things have changed in the last thousands of years. It’s a matter of time, gravity, and the shear scale of the universe. It’s almost impossible to comprehend how big it is (that’s what she said).
